Paul McCartney keeps forgetting how to play Beatles songs

Paul McCartney admitted that he can’t remember how to play all the Beatles songs - "I have to re-learn everything. I’ve written an awful lot, you can’t retain them all", he told The Mirror. He says he has to rely on bandmates and listen to some of the deeper cuts that he hasn’t played in a while. McCartney is also currently working on his first musical, an adaptation of 'It’s A Wonderful Life'.
