Don't you think it's sometimes wise not to grow up.

You don't always do the same things you've done the night before. That's what makes playing live so interesting as opposed to being in the studio.

Boys were a very essential part of rock & roll. The girls were more onlookers.

I don't spend money on anything. I don't collect anything. I don't spend it on furniture.

I wasn't taking so many drugs that it was messing up my creative processes. It was a very good period, 1968 - there was a good feeling in the air. It was a very creative period for everyone.

I liked John a lot. He was the one I really got on with the most. We weren't buddy-buddies but we were always friendly. But after the Beatles and the Stones stopped playing clubs, we didn't see each other that much until he separated from Yoko, around 1974. We got really friendly again. And when he went back with Yoko, he went into hibernation ... when I went to visit someone in the Dakota, I'd leave him a note saying: 'I live next door: I know you don't want to see anyone, but if you do, please call.' He never did.

I must be careful not to get trapped in the past. That's why I tend to forget my songs.
