There will be no wardrobe malfunction with me. I can promise you that.... I have nothing I will be exposing or taking off.

I did cocaine for about a year around the time of Sgt Pepper. Coke and maybe some grass to balance it out. I was never completely crazy with cocaine. I'd been introduced to it and at first it seemed OK, like anything that's new and stimulating. When you start working your way through it, you start thinking: 'Mmm, this is not so cool an idea,' especially when you start getting those terrible comedowns.

It's also not unusual for writers to look backward. Because that's your pool of resources.

Domesticity is the enemy of art. I don't know if that's true. You can write good happy songs. So, I don't think it's necessarily happiness. But I think self-satisfaction is maybe the enemy. It's kind of better to think, "Tomorrow night I'm gonna sing it better." There is this forward effort. It feels to me right, it feels human.

One of things about beards is that, when men reach a certain age, they'd like to see if they can grow one. It's a phenomenon I understand very well. After you get over the itchy face, you go, "Oh, I don't have to shave, that's cool." And then you move into the philosophical thing- people say, "You look weird, you have a beard." And you say, "No, actually, it's weird to shave." Having a beard is natural. When you think about it, shaving it off is quite weird.

A lot of the Beatles albums were very various, and we did it on purpose: We didn't want the next track to sound like the last one.

I think the 'Just say no' mentality is so crazed. I saw a thing in a women's magazine the other day. 'He smokes cannabis, what am I to do? He laughs it off when I try to tell him, he says it's not really harmful...' Of course you're half hoping the advice will be, 'Well, you know it's not that harmful; if you love him, if you talk to him about it, tell him maybe he should keep it in the garden shed or something,' you know, a reasonable point of view. But of course it was, 'No, no, all drugs are bad. Librium's good, Valium's good. But cannabis, ooooh!' I hate that unreasoned attitude.
