question for an angel series fan

I've been trying to find out what song is played on one episode in season 4, it's the episode after angel (or angelus) killed the beast and broght back the sun, he's in a bar having a drink with some vampires... i also heard it on angel's promotional video in season 1... i don't know if this can help to find out what song it is.
Well i hope it does the trick... bye
PD: Excuse my english, i'm a little rusty, it's been a while since i wrote something in english (i'm from latin america, Chile to be exact)... well... peace, i'm out
