We went to America a few times and [Brian] Epstein always tried to waffle on at us about saying nothing about Vietnam. So there came a time when George [Harrison] and I said 'Listen, when they ask next time, we're going to say we don't like that war and we think they should get right out.' That's what we did.

My father and mother split and I never saw my father until I was 20, nor did I see much more of my mother.

I used to be cruel to my woman, and physically - any woman. I was a hitter. I couldn't express myself and I hit. I fought men and I hit women. That is why I am always on about peace, you see. It is the most violent people who go for love and peace. Everything's the opposite. But I sincerely believe in love and peace. I am a violent man who has learned not to be violent and regrets his violence. I will have to be a lot older before I can face in public how I treated women as a youngster.

I felt that film (Let It Be) was set up by Paul for Paul. That is one of the main reasons the Beatles ended. I can't speak for George, but I pretty damn well know we got fed up of being sidemen for Paul. After Brian died, that's what happened, that's what began to happen to us. The camera work was set up to show Paul and not anybody else. And that's how I felt about it.

All music is rehash. There are only a few notes. Just variations on a theme. Try to tell the kids in the Seventies who were screaming to the Bee Gees that their music was just The Beatles redone. There is nothing wrong with the Bee Gees.

We reckoned we could make it because there were four of us. None at us would've made it alone, because Paul wasn't quite strong enough, I didn't have enough girl-appeal, George was too quiet, and Ringo was the drummer. But we thought that everyone would be able to dig at least one of us, and that's how it turned out.

I am like a chameleon, influenced by whatever's going on. If Elvis can do it, I can do it. If the Everly Brothers can do it, me and Paul can. Same with Dylan.
