John Lennon (in 1980) - "Paul again. He had a little spurt just before we split."
Paul McCartney (in 1994) - "It's rather a sad song. I like writing sad songs, it's a good bag to get into because you can actually acknowledge some deeper feelings of your own and put them in it. It's a good vehicle, it saves having to go to a psychiatrist. Songwriting often performs that feat-- you say it, but you don't embarrass yourself because it's only a song, or is it? You are putting the things that are bothering you on the table and you are reviewing them, but because it's a song, you don't have to argue with anyone... It's a sad song because it's all about the unattainable; the door you never quite reach. This is the road that you never get to the end of."
