Top badass moment? Has to be Danny arguing with a pub owner and a bouncer, demanding a £30 payment for the band's appearance. When he got nowhere he clobbered the bouncer with an electric guitar and ran off. Trashing your kit is always rock 'n' roll and therefore always badass, even if smashing up it is a bit stupid and you're not even in the band anyway. Hitting a bouncer is probably not the brightest thing to do either. 0 cats and 0 decapitations.

Not-bad rock movie

Pretty good.
