Hmmm we could always start the game with it being 4 hours to show time at the bar.  Band members arriving one at a time to do a little socializing and have a couple of drinks before they begin to prepare for the evening performance.  I'm thinking for their performances at the bar they would take the first set  third set and last set with a couple different bands playing between their sets to give them a bit of a rest instead of just playing all night.  Of course we don't have to play it that way that was what I had been thinking about.
