Reporter: The "Bitch" solo is in a Chuck Berry style...
Keith: Which I do every night.
Reporter: ...and the beat turns around several times. Was that completely spontaneous, or semi-planned?
Keith: Maybe listeners knew a year or six months later that the beat turned around, but at the moment I wasn't conscious of that. It comes so naturally, as it's always happened, and it's always given that extra kick when the right moment comes back down again. That's what rock and roll records are all about. I mean, nowadays it's "rock" music. But rock and roll records should be two minutes, 35 seconds long, and it doesn't matter if you ramble on longer after that. It should be, you know-wang, concise, right there. Rambling on and on, blah blah blah, repeating things for no point-I mean, rock and roll is in one way a highly structured music played in a very unstructured way, and it's those things like turning the beat around that we'd get hung up on when we were starting out: "Did you hear what we just did? We totally turned the beat around [laughs]!" If it's done with conviction, if nothing is forced, if it flows in, then it gives quite an extra kick to it.
