John Lennon said, “When I’m Sixty-Four was something Paul wrote in the Cavern days. We just stuck a few more words on it like ‘grandchildren on your knee’ and ‘Vera, Chuck and Dave’. It was just one of those ones that he’d had, that we’ve all got, really; half a song. And this was just one that was quite a hit with us. We used to do them when the amps broke down, just sing it on the piano.”
