When Yoko [Ono] and I got married, we got terrible racialist letters - you know, warning me that she would slit my throat. Those mainly came from Army people living in Aldershot. Officers.

I believe that God is like a powerhouse, like where you keep electricity, like a power station. And that he's a supreme power, and that he's neither good not bad, left, right, black or white. He just is. And we tap that source of power and make of it what we will. Just as electricity can kill people in a chair, or you can light a room with it. I think God is.

He laid it on George, me and our wives without telling us at a dinner party at his house. He was a friend of George's, and our dentist at the time. He just put it in our coffee or something. He didn't know what it was, it was just, 'It's all the thing,' with the middle-class London swingers. They had all heard about it and didn't know it was different from pot or pills. And they gave it to us, and he was saying, 'I advise you not to leave,' and we thought he was trying to keep us for an orgy in his house and we didn't want to know.

We all have Hitler in us, but we also have love and peace. So why not give peace a chance for once?

Instant Karma is going to get you.

Trying to please everybody is impossible - if you did that, you'd end up in the middle with nobody liking you. You've just got to make the decision about what you think is your best, and do it.

Life is very short, and there's no time for fussing and fighting my friends
