Metallers GWAR play their cover of Kansas' "'70s derivative crap rock". Pretty strange stuff, but one of the most entertaining covers in this long running series. Plus, you have to admit the riffs in that tune are pretty good.
Everything, the walls, the ceiling, the floor, covered in plastic wrap, and for good reason, because let's face it, when you go to see GWAR, no matter how hard to try to hide, you will get messy.
