Why would I retire? Sit at home and watch TV? No thanks. I'd rather be out playing.

If anyone had told me in the '60s that 20 years later we'd still be talking about whether pot was worse than this or that, I'd have said, Oh, come off it, boys.

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.

I feel like the sixties is about to happen. It feels like a period in the future to me, rather than a period in the past.

If anyone wants to save the planet, all they have to do is just stop eating meat. That's the single most important thing you could do. It's staggering when you think about it. Vegetarianism takes care of so many things in one shot: ecology, famine, cruelty.

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.

When you were young, and your heart, was an open book. You used to say, live and let live.
