It's a powerful thing hearing your friend on a very beautiful song.

You see, my mother was a district nurse until she died when I was 14, and we used to move from time to time because of her work.

It's also not unusual for writers to look backward. Because that's your pool of resources.

I'm still looking to write a great song.... You always are. You know, you never think, 'Well, that's enough ... that's good enough.'

I love the past. There are parts of the past I hate, of course.

Someone like John would want to end the Beatle period and start the Yoko period. He wouldn't like either to interfere with the other.

At the end of the Beatles, I really was done in for the first time in my life. Until then, I really was a kind of cocky sod.
