AC/DC rock legend Malcolm Young was spotted out and about in Sydney's King's Cross on Monday morning.

The founding member of the legendary Australian rock group, 62, who recently disclosed that he has been diagnosed with dementia, cut a delicate figure as he strolled through the city centre neighbourhood.

The guitarist and songwriter was dressed casually in a pair of faded denims, a black T-shirt and grey hoody top, as he walked accompanied by a friend, in the sunshine.

Keeping the cooler autumnal climes at bay, the greying musician wore a dark beanie as he strolled along, not far from the Elizabeth Bay care home where he is reported to reside, splitting his time between the facility and his home.

In September last year Malcolm announced his retirement from the band, amid months of speculation and concern about his on going health problems.

Then in December the famously private star and his band revealed his battle with dementia, with his brother Angus, 60, explaining he'd been showing early signs as far back as the band's Black Ice World Tour in 2008.

The lead guitarist said in an interview with Guitar Magazine that they hoped Malcolm would show signs of recovery but he didn't.

The Highway To Hell star is young for a dementia sufferer with over 65s normally afflicted, although it's not unknown for people to experience the disease, which leads to memory loss, in their 40s and 50s.

In ABC's 7:30 report in December, Angus said he had realised their was something wrong with his brother when he became confused and disorganised during the song writing process, which historically the pair has always shared.

'Mal kept up right up until he couldn't do it no more,' Angus told the 7:30 report.

It was Malcolm who convinced the band to continue touring and making music, hiring Steve Young the pair's nephew as his replacement.

'It was a strange feeling because your work mate, you worked with for the last, for me 35 years wasn't there anymore,' added lead singer Brian Johnson.

It was then AC/DC stayed together and put out their next album - their first without Malcolm - entitled Rock Or Bust.
