Will you still need me, will you still feed me, when I'm sixty-four? - Paul McCartney

For you know that it's a fool who plays it cool, by making his world a little colder.

For cruelty to animals, vegetarianism is the great thing to get rid of that. For the planet, to prevent depleting the water and the land and everything, it’s a great idea. And I think it’s a great thing for your health, and doctors nowadays agree with that. There are plenty of great books and organizations, so no matter where you are, there is someone to help you. That’s your first step, and I think your second step is just look in the supermarket for good vegetarian food, and I think it’s so much more readily available now.

One of the things I always thought was the secret of The Beatles was that our music was self-taught. We were never consciously thinking of what we were doing. Anything we did came naturally. A breathtaking chord change wouldn't happen because we knew how that chord related to another chord. We weren't able to read music or write it down, so we just made it up. My dad was exactly the same. And there's a certain joy that comes into your stuff if you didn't mean it, if you didn't try to make it happen and it happens of its own accord. There's a certain magic about that. So much of what we did came from a deep sense of wonder rather than study. We didn't really study music at all.
