My cover band accepted a gig on a day that I'll be out of town. We have a band calendar and I had my unavailable dates on it a couple months before the opportunity came up. I've always played in originals bands and have never dealt with having a sub come in. How much should I expect to show him "the ropes"? Or should the band worry about that since they scheduled the gig knowing I wasn't available. The sub is a great player and I know he is capable of playing, but we play a some songs in different keys and different arrangements. Just looking for opinions since this is new to me. Thanks.
