I hate to sound like Julie the cruise director but it's people that I think about all the time.
Most of the people I know in bands, all they are concerned about is getting to do the next record.
I like to do little obsessed losers, or people who are in over their head, or people who are trying to figure stuff out, or guys whose girlfriends leave them and they don't quite get it. Guys who just don't quite get it.
