800 lb gorilla

kid brother has a good fucking band and they have a big show at the TOWN POOL in a month and have to play for four hours and are in need of songs to cover. right now they do some originals (which sound like ramones + zappa + the who + sabbath) and they also cover "smells like teen spirit," "layla," "iron man" etc. my bro is the drummer (and he's pretty damn good), their bass player is v good (and 12!!!), their rhythm guitarist sucks and their lead guitarist/singer can seriously shred (no joke)(but can't sing a lick and hasn't really learned to yelp yet). so anyway some song suggestions would be great -- i'm putting together a cdr for him of stuff they should consider. help pls! also i have some video of them playing somewhere and i'll try to post. thx yall.
