I played with my church worship band last sunday, it's a modern style worship led by the band. I know it sounds dorky, but the guitarist is a great musician and bandleader. (The bass-played was 16 or 17) There is a junior-high (50-150 kids) and senior-high (100-300) service each week and along with the teaching and other parts there is worship as well. Well it was my first time to play live with any band, but the junior high service was a little bit nervous but we didn't screw up any songs as far as the audience could tell. So going into the 2nd service I was more confident, as we began the first song I could feel myself getting into the groove...but then it all went wrong. I'm not sure what happened, I think the bass player hit a wrong note or something but him and the guitar got thrown off and couldn't recover...there I was drunnimg away until the guitarist stopped all together and look at me with a look that had me stumped for what to do. So I did some crappy fill in an attempt for them to play off me and start up again....but I just sat there and listened to him tell the audience how many times we had rehearsed that song. After that I didn't make any mistakes, I wouldn't let myself. The rest of the service was much more solid than the first (other than the first song at least). He was kind of mad at the whole debacle but understood that it can happen, he told me that I'll have a chance to play with him in the future.
But it went pretty well for a first time, what a rush to play for an audience too.
