The band plays. And they rock. They've got two guitarists — that's not new. And two drummers, which is pretty cool.

But on top of all that they've got a sheep in the band. Yes, a sheep. As in, "baa, baa." I am serious.

It's a first for rock 'n' roll and her name is Marby. The sheep bounces on stage, totters at the front near the crowd, raises itself on its rear hooves and is promptly dragged into the moshpit by a bunch of beery longhaired lunatics. But Marby is not ripped apart as part of some heavy-metal sacrifice — later she's even spotted cradling a beer at the aftershow party.
