If having former greats Ricky Ponting and Steve Waugh around the Australian cricket team wasn't intimidating enough for England, the last surviving member of Sir Donald Bradman's Invincibles, Neil Harvey, is attending the second Test at Lord's.

Key points: Neil Harvey was the youngest member of Australia's 1948 Invincibles side

The 90-year-old-said it will be his last visit to the famous venue where he captained Australia, for the only time in his career, in the second Ashes Test in 1961.

"I've got lovely memories there over the years," Harvey said.

"It's my favourite ground — I've realised it's the home of cricket and I appreciate all that history of the place it's got and I just love going back there.

"Every time I walk through those Grace Gates I get turned on, there's no doubt about it, it does something to me."

An attacking left-handed batsman and a brilliant fielder, Harvey made 153 against India at the MCG as a 19-year-old, in just his second Test, in 1948.

He still holds the record as Australia's youngest Test centurion.

"I'm surprised nobody has done it since but I dare say it'll happen one day," he said.

"It's a proud memory to have and it's something that's not talked about too much, so we'll leave it at that."

Soon after that innings, Harvey was selected for the Ashes tour in a team that's still considered Australia's greatest ever to tour England.

"One of the best tours I've been on because it was my first tour and the captain was Don Bradman," Harvey said.

"I never ever thought I'd get a game in the Test matches because that batting line-up as the way it was, I couldn't see myself getting off the 12th man bench.

"As it happened I got a game in the fourth Test, things turned around and I've never looked back since."

In his Ashes debut, the Melbourne-born Harvey made 112 in Australia's seven-wicket win over England, at Headingley.

Bradman's squad featured greats like batsmen Sid Barnes and Arthur Morris, all-rounder Keith Miller and paceman Ray Lindwall.

In their 34 matches on tour, the Australian's did not lose a game — a feat which saw them dubbed The Invincibles.

In total, the touring party spent 220 days away from Australia.

At the crease with The Don

Every Australian player on that 1948 tour wanted to share the crease with Sir Donald Bradman.

Harvey only got a couple of opportunities to do so, but said batting with The Don was like "living the dream".

"It was just a pleasure to get up the other end and watch him — he was twice as good as anybody else," Harvey said.

"If you can't get out there and watch and learn something, well there's something wrong with you.

"He was a joy to watch and a great bloke to get on with."

Steve Smith's recent innings of 144 and 142 in his comeback to Test cricket at Edgbaston have led some to compare his exploits to those of Bradman.

"He showed a lot of resolve — he must've got a lot of heckling from the crowd, he just put his head down and made runs. He's come out and he's pleased everybody and maybe even a few Poms," Harvey quipped.

"He's a top player, that fella; he's a really top-class player."

Harvey hinted that Smith wouldn't have been out of place in Australian teams during his era.

"I think if you're a great player in any era you can fit in somewhere no matter who you're playing with or against but I'm not one to compare people you just can't do it," he said.

"The game changes so much. You take the cricket bats today, I think they're unfair, they're too much in favour of the batsmen."

Harvey finished his Test career with 6,149 runs at an average of 48.41 from 79 matches.

He made 21 centuries and 24 fifties and was named in the Australian Cricket Board's team of the century in 2000.

The 1948 legacy

For all of his achievements, Harvey's career was defined by being the youngest member of the 1948 Invincibles.

"I still think it's being used as a yardstick for all the other teams," he said.

"They were such a great bunch of blokes. I was 19 and the next youngest was 26 — they just treated me like I was one of them and gave me all the help I could possibly have.

"And as we all know it's probably one of the greatest cricket teams to play for this country."

It brought a smile to Harvey's face when he saw four left-handed batsmen in Australia's top six for the first Test on the current Ashes tour.

"They're getting more and more of them, aren't they?" Harvey said.

"I'm pleased they gave that Tasmanian bloke [Matthew Wade] a go."

And when it comes to the result of the second Test, Harvey provides the sort of prediction one would expect from an Invincible.

"I just cannot see Australia losing, I really can't," he said.
