They're a good time. I saw them for the first time at the Dennis Dannell (of Social D fame) Benefit Show after his death. They're a classic opening act for old school punk show on the West Coast and Vegas.
They're like Me First and the Gimmee Gimmee's (all cover songs) except that they pick a random audience member out for each song and throw them up on stage to sing the song. Generally, the singers are horrible, but every now and then you can get some pretty entertaining stuff. Lot's of old school punk stuff and some crazy covers. I saw a sick version of "Alternative Ulster" once.
