At her beauty zenith...
Had a poster of her on the ceiling above my bed as a teenager. Never managed to hit it, but I certainly enjoyed trying!!!
RagViv Albertine from The Slits. Not the most conventionally beautiful woman. That would be Debbie Harry. But definitely has something. Her autobiography was good too.
And in the the interests of fairness and balance, if I was a woman or a gay/bisexual bloke (which I am not) and this thread was about the most beautiful men in the world of music, I'd probably vote for Terry Hall.
