Does this challenge make sense? For example, I could have gone for Alice Cooper in Wayne's World, or Rush in I Love You Man - two films I have already featured here.
The one I've chosen for today is a slight cheat - Lemmy in the film Airheads. It is a slight cheat because he is credited in the titles as "Lemmy von Motörhead". However, it is close enough for this purpose and gives me the excuse to link to this track from the soundtrack:
The video quality is pretty poor but close your eyes and enjoy Lemmy doing what he does!
To be honest, I could do without the Ice-T bits... but you can't have everything.
