Uncredited bands that are in this and other credit issues....
The Weirdos, the Dicks, and I think the Mutants.
The Dicks are the band with the singer breaking a mirror, opening an umbrella, etc.. This is not the Texas band, but the SF performance art band that played with punk bands. The Weirdos are the band on stage during Lust For Life. Iggy Pop is NOT in this movie.
The bearded "fake" punk band (with the singer that has a huge safety pin) is probably the Hollywood Squares or the Child Molesters (both bands have released records).
The version I saw does not have Joe Strummer in it, though I know there are a couple of versions of this movie.
This movie make American punks look stupid (mostly)!
