Maybe get hold of a wave editor like Sound Forge or something, that way you can chop out the bits you don't want. I'd suggest to your singer that he might want to be a bit bolder with his tunes, a lot of them stick too close to the guitar line - maybe try just singing the same verses through a few times, trying out different tunes, until you find something a little more unusual. Also - I'm trying to be constructive here, honestly - the lyrics are pretty bad! Not that I'm any better at writing words myself.

I'll look forward to hearing them then! It's also worth spending an hour or so making the best mix possible, whether on a computer or a 4/8 track recorder. As tempting as it is to just wack it on myspace straight away, it's far more satisfying (I find anyway) to make sure it sounds pretty decent and the basic levels are good first.
