Sir Paul McCartney has had the same dream that he's flopping on stage for 50 years.

The Beatles legend might have been attracting massive crowds to his shows for more than five decades, but the 75-year-old musician is left in " cold sweats" at the thought of turning up to perform and stadiums full of people getting up and leaving.

McCartney - who has four adult children with late wife Linda and 13-year-old Beatrice with second spouse Heather Mills - admitted: "Ever since I started performing there is a dream I still have which is you are in a stadium playing with The Beatles or with this band and people start leaving and it is like 'OK what are we doing wrong' we try to pull out the big ones but they're still leaving. You wake in a cold sweat."

The 'Come Together' hitmaker is currently in Australia for his sold-out 'One On One Tour'.

It's the first time in nearly 25 years that McCartney has paid a visit to the country, the last time was for his 'The New World Tour' in 1993.

The 'Four Five Seconds' star still looks forward to performing all of the iconic Liverpool band's classic hits as he likes to "rediscover" them each night.

He's particularly fond of the uplifting reaction he gets from playing 1968's 'Hey Jude', which was originally called 'Hey Jules', and was written by McCartney to comfort John Lennon's son, Julian, during the late frontman's divorce from his mum Cynthia Lennon, which was granted in November 1968 on the grounds of Lennon's adultery with his now-widow Yoko Ono.

On playing the tracks time and time again, McCartney - who with Ringo Starr are the only surviving members of the band, which was also comprised of the late George Harrison - told ABC: "It's like rediscovering them.

"When everyone is singing 'Hey Jude' it is like we all don't care about the bad news and are concentrating on this great little moment."
