Ooh, I dunno, Siouxsie Sioux smoked like a trooper when she was making "The Scream", and she hits some pretty good high notes on that (I'm thinking of, ironically, "Nicotine Stain"). I think with music in general, anyone worth their salt would be able to work with their "limitations" and come up with something even better. I get the idea that you're quite a taskmaster with yourself - if so, that's good, cos it means you can push yourself more and more. There's no point doing something in a half-assed way, is there?
