guy from the local band you saw who can't sing, etc. by far.
personal example: battle of the bands my school had last week. the final group's set ended, but their damn scruffy hobo-man of a lead singer went back with his guitar and played for another 20 or 25 minutes by himself. and then made the band come back up. and they played two or three more songs. then they finally got the hell off stage, and the winners were announced. then i got to wait around for everybody to leave before i could start doing my job- resetting the room with 500+ chairs for an event the next day. we had to stay at work til 11pm that night, and then i spent most of my shift the next day on it too. *grumble*
the band, by the way, was Citizen Cope. i have no idea what the hell they were doing at umd's battle of the bands.
