AC/DC's lead singer Bon Scott visited two different women in the same maternity ward after they gave birth to his children at the same time, reveals a new book about the Australian rock band.

According to the band's previous manager and author of 'Dog Eat Dog', Michael Browning, neither woman knew of the other's existence.

In his tell-all book, Browning reveals intimate snapshots of the musicians lives in the five years he spent with them.

'This was one if those moments when Scott had strayed a again into the dark world of drug taking,' Browning told the Daily Mail Australia. 'On this occasion he was given a dose of heroine by a couple of young ladies which made him turn a particular shade of green.

'They tried to revive him by giving him a kind of amphetamine and when that didn't work, they carted him off to the hospital where he recovered.

'When I visited him the next day in hospital, he was kind of chirpy and having a bit of fun with a couple of the nurses, then he made the comment that the last time he was in hospital was to visit two women who were both having his babies.'

Did he keep in contact with those women?

'I don't know, I don't think so, I think they were just some of his many "liaisons,"' said Browning. 'But it does beg the question, where are the siblings? And I can say there are at least those two out there.'

'Dog Eat Dog' is Michael Browning's account of his five years managing legendary Australian heavy rock band AC/DC, charting their rise and his fallout with the band members

According to Browning, Scott was a 'real lady's man'. It was all part of the Sex, Drugs and Rock and Roll that was the Australian music scene in the 70s and 80s.

He tells how Scott wrote the lyrics of 'Whole Lotta Rosie' about a 'fairly large-sized girl' he was sleeping with:

Ain't no fairy story, Ain't no skin and bones, But you give it all you got, Weighin' in at nineteen stone, You're a whole lotta woman goes the song.

'He was quoted as saying once that the reason he had his way with Rosie was that, given her rather large size, the likelihood of him catching the Clap was minimal. 'Of course, Gonorrhea was the dreaded disease of the times.'

But he wasn't all bad, even if he 'certainly had a colourful life style,' says Browning.

'Bon's liaisons were probably more enduring than the other members of the band; he gave them more time if you like,' tells Browning. 'He was very gentle and nice to the girls; he was a good listener and a prolific letter writer and the girls love him for it.'

'This kid barely looked 16' says Browning of guitarist Angus Young, who's seen here at one of the group's earliest performance, all bare-chested and shuffling through the crowd as he launched into some high voltage heavy rock

Michael Browning helped propel AC/DC onto the international stage after first spotting the band in September 1974, when they were booked to play at his Melbourne Club The Hard Rock Café.

'Bon turned up with two bottles of bourbon, some dope and some speed. When Angus (Young) saw this stash, he said to Malcolm, 'If this guy can walk, let alone sing, it’s going to be something',' he said.

'They were raw and rough, and much of the crowd, Michael included, were bewildered by the flashy guitarist dressed as a school kid,' he tells the story.'I went downstairs to where the bands play at Hard Rock Café and discovered this little kid with a school uniform walking around, looking lost with a cigarette hanging out the corner of his mouth and this other little kid dressed up in what could only be described as a jockey’s outfit with a satin shirt and trousers and high boots.

'Honestly I was just wondering, this can't be the band, what the hell had I booked?

'Then they started playing and I was just totally taken back, Malcolm’s classic guitar intro kicked in and then Angus kicked in and it was wow, I was pretty much hooked from the first couple of minutes.'

'Bon's (pictured) liaisons were probably more enduring than the other members of the band; he gave them more time if you like,' tells Browning.

An important part of Browning's push to achieve overseas success for AC/DC was to make sure they acted like rock stars, including setting up photo opportunities like being handed keys to the city here in North Miami on their first US tour

Once Browning had locked AC/DC into regular gigs at the Hard Rock Cafe in Melbourne their popularity took off. The venue would also play host to other lead acts like Billy Thorpe & The Aztecs, Split Enz, Daddy Cool and Richard Clapton

But in this extract from the book, Michael Browning reveals how his life with AC/DC came crashing down.

'North America, May 1979 - AC/DC had just flown in from London, where they’d recorded their latest album with their new producer, Robert ‘Mutt’ Lange,' Browning said.

'There’d been a treacherous lead-up to the recording, including the heartbreak created by the band being forced to move on from their long and close-knit relationship with Harry Vanda and George Young, AC/DC’s record producers, mentors and, in George’s case, family.

'Their new record label, American powerhouse Atlantic Records, said it had to be done and I somewhat reluctantly agreed, making me complicit in the decision. So far, this big change had claimed four scalps. It was a difficult and emotionally charged transition for all of us.

'I’d been managing the band since 1974, during which time constant touring and good old-fashioned word of mouth had established AC/DC as an international force to be reckoned with.

'But mass radio airplay had eluded them and it had become essential to make an album that would change this. This was our shot at the big time. It wasn’t going to be easy.

'The band and I met in my New York office and we listened to the Highway to Hell album. Not only did it completely blow me away, but it contained that one track, the title song, that I knew was the missing link, the song that would establish the band internationally, break them wide open. So why was I picking up a strange and uneasy feeling?

'The next day I met with Bob Defrin, Atlantic Records’ art director, with whom we’d developed the now famous AC/DC logo. We arranged a photo session for the new album’s cover, another important piece of the puzzle.

After the heady days of AC/DC ended by Michael Browning he went in search of new Australian music talent and before long had signed INXS, seen here in the recording studio, to his record label

'After a few days’ rehearsal at SIR Studios in New York, the band started their two-month tour of the US. This tour, along with their new album, would propel the band to a whole new level; we all sensed it. On 22 May, I flew to Nashville to join the tour.

'The band was playing the Tennessee Theatre; we’d come a long way since I’d first sighted them at the Hard Rock Cafe, my club in Melbourne, and set out on this shared journey of world domination.

'After the gig the band came off stage and into the dressing room, and straight away I knew something was amiss. The atmosphere was very chilly.

'I can’t remember what started it, but an almighty argument erupted between the guys and myself. Malcolm and Angus Young were like a pair of rampant pitbulls, tearing into me. A number of issues were tossed around, including the sacking of Harry and George. Mutt Lange had helped them achieve something incredible, but the band had had a gutful of the drama.

'I’d taken on a partner they didn’t approve of, and had come to dislike spending so much time on the road—these were other volatile issues that bounced around the Nashville dressing room.

'Singer Bon Scott and drummer Phil Rudd also threw a few choice words into the donnybrook, while bassist Cliff Williams, who by rights should have erected a statue of me in his backyard, remained absolutely silent.

'Quickly, the gut-wrenching realisation set in. Here I was, in Nashville, the middle of nowhere, getting sacked by the same ungrateful little f*#!#@s that I’d grown to love over the past five years.

'Until now, I was the one who did the sacking. But AC/DC’s dog-eat-dog mentality had claimed a new victim. Me. And I was devastated. Life as I had come to know it was about to change in a huge way.'

AC/DC played hard and bargained hard on occasions, Browning recalls the end 'until now, I was the one who did the sacking. But AC/DC’s dog-eat-dog mentality had claimed a new victim. Me. And I was devastated. Life as I had come to know it was about to change in a huge way'

He gives a sense of how hard they lived on and off the stage in this account of Bon Scott.

'It is fair to say he had two sides to him,' said Browning.

'He was a very, very gentle loving person and prolific letter writer and would remember his friends and was very popular with whoever he met - the other side was he would occasionally get fairly out of it on fairly heavy drugs and alcohol and end up in hospital.'

Browning goes on to explain he 'survived to tell the tale', sadly unlike some of those he would help on the way to super-stardom; Billy Thorpe, Bon Scott and Michael Hutchence.

While their deaths 'hit me hard', he admitted, it's the sad struggle of AC/DC guitarist Malcolm Young with dementia, which seems to have affected him most.

'Malcolm is very, very upsetting for me personally because I have always had a fabulous relationship back in the days when I was managing the band, up until the end of course,' he said.

'We made a pretty good team, I discussed everything with him and he would then go back and discuss it with the band, we had a good thing going. I enjoyed working with him and liked him very much.

'Then all of a sudden becoming persona non-grata, for business reasons, that’s just the way they operate I’d always.

'Even though it happened (the split with AC/DC) many many years ago, I always imagined that one day we would just sit down and have a drink and have a laugh about things happened during that period and have a good time and regretfully that’s now out of the question.

'It’s a very, very unfortunate and sad situation.

'All of them hit hard. Billy, that was very unexpected, that came out of the blue, had no idea that was coming.

'Bon? You could kind of get a sense that it was inevitable I mean he used to always say it was going to happen.
