I'm not a huge GWAR fan, they make a few good singles and I hear their live show is amazing, but that about it. Although their newest album had this version of Alice Cooper's "School's Out," which is fantastic. It's so good it made my list of 20 Cover Songs That Are Better Than The Originals, from a few months ago. I like the heavier feel of the song, and I really enjoy the extra psudo-verse they add right at the end. It makes me laugh every time.
Enjoy ("Schools out for summer Kiddies...")
