Reply #19: It's hard to keep the chronology straight...

... but I think Bowie was well into glam before Roxy took it up. Certainly before "For Your Pleasure" Bowie was doing it. I've seen enough of Ferry to be easily sold that he could not top Bowie in his depictions.

Of course, Bowie is said to have ripped it from Marc Bolan, and that is probably true.

Fact is, even though I'm an Enophile of the highest order, I never found Roxy very compelling - so my knowledge of who did what when is not that great :) and of course, being "first" is not necessarily being "best".
