Have you noticed that elderly rock-stars such as Jagger, Bowie,Tyler, Plant,Cooper,Dylan Osbourne and Page etc have such plentiful hair?
Have they all made a pact with the Devil in return for none-baldness or is it something to do with the rock and roll life-style?
I don't know. But I want some of it.

I think it's because they have the money for hair implants.

A couple of lines from a Sex PisTOls tune "Rock and Roll Swindle": "Mick Jagger white nigger, Elton John hair transplant!".
