My guitarist cancelled two upcoming shows five days in advance due to a bad back. OK - so we called and got a sub. He agreed and learned 18 new songs in a few days. He shows up at the gig and the regular guitarist shows up demanding to play and get paid. BTW - he's all hopped up on Flexeril, Vallium, and Vicodin for his back. Now "the band" wants to screw over the sub guitarist and pay the regular guitar player for the night. I'm ready to find another band. The sub guitarist just said "I think I'll get going" when he saw what was going down. BTW - the sub is a full-time pro musician and has a family. Opinions?
