lol, Stillwater is a fictional band. ^_~ Those guys in the movie? They were actors. It's based on the director's teenage years, but it's still not real. AFAIK Stillwater is supposed to be a "typical almost-bad 70s rock-band with one hit".
Sorry I discouraged you... just having a fit of temper. It's my second favorite band being copied for use in a "typical bad 70s rock band", which gets my fannish blood pressure up.
Errr. Sorry about that part then.
