The film footage, collected from all over the world, is a must for any Wings fan.
Following the album and film release he will return to LA to finish off the forthcoming album due out at the end of the year.
But, Paul, who will be 59 on June 18, releases Wingspan on May 7 and the soundtrack album will sell for the price of a single album.
Paul, who is currently in New York with girlfriend Heather Mills, has been reading from his Blackbird Singing book and speaking out against the dangers of landmines.
The Wingspan film, he points out will make, 'great telly' in the US when it screen on May 11 and here in the UK on May 19 at 10pm (C4).
Three years in the making, it emerged after Paul and Linda were looking at home movies and photographs. Alistair, husband of Mary McCartney, put the film lovingly together and added some never-seen-before footage of the band on stage.
Having seen a sneak preview of the film it candidly reveals how Paul and Linda raised a young family and fronted a new band against the massive handicap of battling The Beatles legacy, a pot bust in Japan and two key releases being banned by the BBC.
It was the hardest job in rock and roll and yet, in the space of nine years, Wings soared to international success with 17 million selling-singles, five USA no 1 albums and eventually a US stadium tour that broke the Beatles attendance record at Shea Stadium.
Sir Paul says that making an Anthology of his Wings days will at last show how important Linda McCartney was in the ever-changing Wings line-up.
"When The Beatles finished it was such a shock to me and my system. Besides being out of work, to my mind I'd lost one of the greatest jobs in the world.
"Once I'd got over that initial shock I thought, ''What am I going to do now. I'm not in The Beatles anymore ... do I even continue in music now, and if I do, do I go solo or get a band or whatever'.
"We did do great with Wings. We did it big and we managed to create a few records, both of the musical type and the attendance type. Wings really allowed me to continue doing music after The Beatles that was the main thing for me really.
"I couldn't stop making music if you paid me so there had to be some way to keep doing it. I really need to do that and so there had to be a band and it was called Wings. That is the story we are telling in the film which is a very human story.
Wings set out to prove that we could do it. There was so much bitterness in the wake of The Beatles break-up that there was an element of 'We'll show you' . . .
