I discovered last night that the booker for a club my band is playing this evening has booked another 3 bands in addition to the 2 bands our band had secured for the evening!
The arrangement was that my band would play and put the evenings entertainment together. We got 2 other bands who all have been advertising the event for about a month now.
The booker must not keep a very organized calendar and didn't realize until the last minute the double booking problem. So tonight should be interesting when 6 bands all show up with gear. Glad I'm not in charge of this. There will probably be a lot of unhappy musicians tonight.
