also, no cover show is complete without "where is my mind" by the Pixies.
I dunno how well it'll go down that side of the atlantic, but summin by Lost Prophets is always good, they are a hooky, dancey band, and maybe "Last train home" is a good choice...if I was there I'd be dancing.
Lets see...throw in the Blink 182 and Good Charlotte..."Stay together for the Kids" "I miss you" and even "Dammit"(such a party song) should all be pretty good tunes there. and "I just wanna live" by GC is awesome.
I'd also keep with what is relevant right now...so I reckon that Franz Ferdinand suggestion is a great one...also, how about "wake me up when September ends" by Greenday...everyone in the world loves them right now...and rightly so.
Oooh, and to add to the Dire Straits score, I'd throw in "Romeo and Juliette"...and ofcourse no school dance is complete without Pink Floyds "Another Brick in the wall"
good luck...and Acapella...what happend to the rapeme?
