Guitar Hero: Van Halen demo hits Xbox LIVE

The word is that Activision’s Guitar Hero: Van Halen has been demo-rized and is now available for download over Xbox LIVE.

One problem: where is it? We’ve been probing the Marketplace like Dick Tracy would whenever he’s not occupied with beating his wife or scoring some smack. Sure, there’s an alleged demo dubbed “Guitar Hero: Van Halen” listed in the Game Demos menu, but this “demo” has a mere two Van Halen songs in it — “Eruption” and “Panama.” Surely, Weezer’s “Dope Nose” and Killswitch Engage’s “The End of Heartache” wouldn’t be included in a real demo for a Van Halen game, right? RIGHT?
