Ok. So my band and two others agreed to do an August 4th outdoor set a couple of months ago during a city music-fest. Its pretty big, and a blast. The two other bands needed a bassist, so ive stepped up, learned their stuff and practiced with them nonstop. My band's lead singer, when we were notified about the gig, said she could do it. Two weeks ago, she calls me and says she cant. I was sympathetic, but she has pulled this stuff before and always, no matter what is said, makes it to the gig. A couple of days later she calls me and says she can do it, and weve been rehearsing since. All was well until today, when I get a call from my guitarist telling me she just backed out of the band completely. I call her, and verify. So now im left with 1.5 weeks to find a singer and teach her my bands set. Nothing like being screwed over, eh? Im posting this for misguided sympathy, suggestions on how to handle THIS situation, and in the future.
