Ok i have found the name of the movie, the name of the movie is The Choirboys.
Sweeeeettt! Gumbyman, you are our hero! :D Let the moustache-ripping begin! :lol:
EDIT: Hmm...okay, I actually just found the Choirboys clip on Youtube and I don't think that's it. :(
Digging a bit deeper into my memory banks - I remember it being just two guys facing off against each other, it wasn't a whole crowd of people there. As I recall, they were in a grungy warehouse or similar kind of wide open, run down location. Also, the guy's moustache was a big, black bushy Mario-esque moustache.
Ringing any bells? Anybody? Anybody? Bueller?
