Rock n' roll! It's the music of puberty.

As Mick Jagger will tell you, performing is an aerobic work-out. I've got the bass guitar, which is the heaviest of all the instruments, and I'm a little girl, in boiling-hot leather under the lights. You have to keep the fitness level up if you want to look good up there.

The bass player's function, along with the drums, is to be the engine that drives the car... everything else is merely colours.
