We're trying to sell peace, like a product, you know, and sell it like people sell soap or soft drinks. And it's the only way to get people aware that peace is possible, and it isn't just inevitable to have violence. Not just war - all forms of violence.

We went to America a few times and [Brian] Epstein always tried to waffle on at us about saying nothing about Vietnam. So there came a time when George [Harrison] and I said 'Listen, when they ask next time, we're going to say we don't like that war and we think they should get right out.' That's what we did.

Where do people get off saying the Beatles should give $200,000,000 to South America? You know, America has poured billions into places like that. It doesn't mean a damn thing. After they've eaten that meal, then what? It lasts for only a day. After the $200,000,000 is gone, then what? It goes round and round in circles. You can pour money in forever. After Peru, then Harlem, then Britain. There is no one concert. We would have to dedicate the rest of our lives to one world concert tour, and I'm not ready for it. Not in this lifetime, anyway.

From our earliest days in Liverpool, George and I on the one hand and Paul on the other had different musical tastes. Paul preferred 'pop type' music and we preferred what is now called 'underground'. This may have led to arguments, particularly between Paul and George, but the contrast in tastes, I'm sure, did more good than harm, musically speaking, and contributed to our success.

I really had a chip on my shoulder, ... and it still comes out every now and then.

I started being me about the songs, not writing objectively, but subjectively. I think it was Dylan who helped me realize that - not by any discussion or anything, but by hearing his work.

The idea of being a rock and roll musician sort of suited my talents and mentality. The freedom was great, but then I found out I wasn't free. I'd got boxed in...The whole Beatle thing is just beyond comprehension ... subconsciously I was crying for help.
