John Lennon (in 1980) - "Paul. He must have had an argument with Jane Asher."
Paul McCartney (in 1994) - "As is one's wont in relationships, you will from time to time argue or not see eye to eye on things, and a couple of the songs around this period were that kind of thing... I would write it out in a song and then I've got rid of the emotion. I don't hold grudges so that gets rid of that little bit of emotional baggage... I think it's my song totally. I don't remember any of John's assistance."
