Either that what song Yaa told you (that is the one played when Bender smashes the concert) or it is "Iron-Man", a song by Black Sabbath (you may know Ozzy Osbourne from them).
Welcome to PEEL,
if you want to know more about songs used on the show you might want to click this link: Futurama - CD
. It never actually was a CD, I just used that thread last year to get pretty much all songs used together.
Also you might want to read our little FAQ on PEEL, giving you few tips and guidelines on how to behave here on our message board. It's a nice read, not too boring The PEELers' FAQ
Enjoy your stay here.
