We were pretty good mates until the Beatles started to split up and Yoko came into it. It was more like old army buddies splitting up on account of wedding bells.

I hate the idea of success robbing you of your private life.

I'm not religious, but I'm very spiritual.

I should be able to look at my accolades and go, "Come on, Paul. That's enough." But there's still this little voice in the back of my brain that goes, "No, no, no. You could do better. This person over here is excelling. Try harder!" It still can be a little bit intimidating.

Painting is similar to music. You get a couple or words or notes or chords that excite you, and you just follow them and add a bit more and see where it takes you. That's the thrill for me. It still is a thrill, which is amazing after all this time.

I used to go round to Aunt Mimi's house and John would be at the typewriter, which was fairly unusual in Liverpool. None of my mates even knew what a typewriter was. Well they knew what it was but they didn't hae one. Nobody had one.

I love to hear a choir. I love the humanity... to see the faces of real people devoting themselves to a piece of music. I like the teamwork. It makes me feel optimistic about the human race when I see them cooperating like that.
