From my experience watching battle of the bands completitions, then you really need to do something a bit different. Last one I saw, I must have heard about 10 Metalica covers (and I've been hearing them for about 10 years).
Unfortunately, I'm away this weekend otherwise I may have come over.
deg0ey - I go climbing at Warwick Uni every now and again. It's only about 15-20 minutes from my gaff. It's a nice campus with some really good bands that come to the Arts Centre. Have fun dude (wish I was still a student

)
