Paul McCartney admits he was shattered after the break-up of the Beatles.
But with the support of his late wife Linda, McCartney finally got motivation back into his life and formed a new band, Wings.
On Sunday, Channel 7 screens Wingspan, a two hour interview with McCartney, in which he tells of creating one of the '70s most successful bands.
"I always thought you couldn't follow the Beatles," McCartney says.
"This is the story and soundtrack to how we set out to do it."
The special features never before seen McCartney home movies recording his attempt to form a back to basic rock band and trying to raise a family.
"It was like starting your career from scratch," he says.
"I'd drive Linda, the kids, our pets and the band around Britain in a van, asking for work. There was no arriving at concerts in police escorted limousines and playing to screaming thousands, like we did with the Beatles."
"This was about arriving at small halls, unannounced, to play impromptu gigs, where people paid 33 cents to come in."
McCartney explains how Wings finally soared to success in the US with hit singles, inclusing "My Love", "Band On The Run" and the Bond hit "Live And Let Die".
"Looking back, I guess I was actually competing with myself," he says.
"It was certainly very hard, but that, I think, is what makes it such a human story."
