First rule of thumb at a Hip show:
Never EVER leave after the first encore.... never. Unless the lights come up, they are coming back...

I'll go one step further: Don't leave until the crew has begun load out.

I went to a Springsteen show in Chicago (around '93 w/o the E Street Band) and he came back a good five minutes after the 'last' encore to play Working on the Highway. About half the crowd had left. I was just about out of the seating area (World Amp) when I heard a roar. Scrambled back to front row (security had basically packed it in) and had Christopher Lloyd (Rev. Jim) and his wife/girlfriend dancing next to me. That was different!
