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.

I think the idea of getting out of a traffic jam and getting out of work each week and going and doing all this stuff would be really exhausting.

Somebody said to me, 'But the Beatles were anti-materialistic.' That's a huge myth. John and I literally used to sit down and say, 'Now, let's write a swimming pool.'

We were a savage little lot, Liverpool kids, not pacifist or vegetarian or anything. But I feel I've gone beyond that, and that it was immature to be so prejudiced and believe in all the stereotypes.

For tomorrow may rain, so I'll follow the sun...

I've got to admit it's getting better. It's a little better all the time.

When you get the money, you still need to keep going; you don't stop. There has to be something else. I think it's the freedom to do what you want and to live your dreams.
