He's on the soundtrack too. T.V. Eye which is the song that Curt's singing in the concert he's introduced in.

Brain Molko is also in the movie, he plays 'Malcom' of the Flaming Creatures at the Death to Glitter concert. (Brian's the lead singer of Placebo. They're also on the soundtrack.) Hope you manage to find it to rent or something. It's a good movie. :)
