I am the drummer / sineger of the Cover-Ups. Jan gave you fantastic advice. Follow those and another thing. Relax mate. It's not the end of the world even if you are not the best of the best. It seems to me that you care waaaaaaay too much as to what impression you leave to people. If you stop thinking like that, you will relax and enjoy. And people will like that and will respond. Never had any lessons and crap like that. but I believe in what I am doing and that's why people love my "singing" and playing and of course the band. But I go out to enjoy myself and kick ass. So think along these lines. "I will kick eveyone's ass today"
