The music's rehearsed a lot. All people think about is, they think, in rock 'n' roll, they get the music off right and they think it's okay standing, looking macho. Well, it's not. That's boring. If you want to be a performer you've got to do a lot more work than that.

There is something I like about talking to journalists that really goes beyond promotion because you aren't just talking to the journalist, but you are talking through them to people who presumably are fans of the Rolling Stones.

I'm very ambivalent in my feelings about marriage. I think it promises a lot to people... sort of like saying, once you get married you are on the highway to heaven, and quite often it isn't that. I think marriage has always been based on a combination of religious and legal reasons.

Samba rhythm is a great one to sing on, but it's also got some other suggestions in it, an undercurrent of being primitive - because it is a primitive African, South American, Afro-whatever-you-call-that rhythm. So to white people, it has a very sinister thing about it.
