Some of my favs:

You’re getting your British ska bands mixed up: he’s the frontman for Bad Manners.
The Edge
Grace Slick
Siouxsie Sioux
Best ever: Iggy Pop
Ziggy Stardust
Marilyn Manson
Eddy Money
Alice Cooper
and my friend Alex Kniepkamp, who went by the name Alix Katt when he was a metal guitarist.
Joe Strummer
Slash
Johnny Rotten
Guy Mann-Dude (obscure, I know)
Iggy Pop

Jello Biafra
Collectively, X wins hands down.

*Worst: *Garfunkel 
Murderface, and Buck Dharma.
Thudlow Boink- thanks- I can’t belive I did that.
Shark Darkwater (They Eat Their Own)
Kyle Kyle (Bang Tango)
My favorite is Ziggy Stardust. And I second Polly Styrene and Iggy Pop too.
Another I really like is Johnny Thunders (New York Dolls).
I know it was given to him by his parents, but I always thought Angus Young was about the coolest rock name, ever.
Oh and Courtney Taylor-Taylor. Hee.
Another one for Alice Cooper, of course.
