The most important ingredient to making a song work is the magic. You've got a melody, you've got words, but on the more successful songs, there's a sort of magic glow that just happens and you can feel it happening. It just makes the songs sort of roll out.

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.

I like most kinds of music. So I haven't got a bag, as they say... except the big black one in the hall outside.

I can't manage without homeopathy. In fact, I never go anywhere without homeopathic remedies.

I doubt very much if The Beatles would have happened if it was not for Elvis.

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.

Putting two songs together, I've always loved that trick when it works.
