I am quite happy that the Beatles came and went. There is even a sort of glory in not having it go on forever. There is a complete body of work that went from A to Z and it is all pretty damn good stuff. The one thing I am particularly proud of is that nearly every single bit of it has some good message. I feel fortunate when I look back. Life is not easy, but I've been very lucky - and I'm touching wood as I say that.

I don't ever try to make a serious social comment.

I don't take me seriously. If we get some giggles, I don't mind.

Animation is not just for children - it's also for adults who take drugs.

There are a lot of artists who haven't lost anything to domesticity. In my case, it probably did happen.

It (LSD) opened my eyes. We only use one-tenth of our brain. Just think of what we could accomplish if we could only tap that hidden part! It would mean a whole new world if the politicians would take LSD. There wouldn't be any more war or poverty or famine.

One of my great memories of John is from when we were having some argument. I was disagreeing and we were calling each other names. We let it settle for a second and then he lowered his glasses and he said: "It's only me." And then he put his glasses back on again. To me, that was John. Those were the moments when I actually saw him without the facade, the armor, which I loved as well, like anyone else. It was a beautiful suit of armor. But it was wonderful when he let the visor down and you'd just see the John Lennon that he was frightened to reveal to the world.
