Think that I would have Gayed it up a bit too but not in the way Hutch mentioned. Less obvious and much younger. After all, I would suspect that the crowd would tend to be on the youngish side. My guess, lots of young girls and younger sort of mainstream Gays.
I do think the St. Etienne, Goldfrapp and Ivy were perfect blends of cool, Gay and near newish though I think that for the St. E song, I would have gone with 'Boy Is Crying'. Just a personal choice.
Not an easy task refining such a show when it's kind of out of your own realm and at the last minute.
Oh, and maybe I'd try to throw some Alt. Rock in there somewhere except that I really don't have a clue anymore what's going on in that genre.
