Activision are intent on luring as many "big name" rock stars to the Guitar Hero brand as possible. Ozzy Osbourne, failing mind aside, is a big name rock star, and a Guitar Hero veteran to boot, providing perhaps the series' finest moment with Bark At The Moon. So it should be little surprise to hear that the ex-Sabbath frontman has been signed to appear in the upcoming Guitar Hero: World Tour, alongside long-time guitarist Zakk Wylde, where they'll be playing Crazy Train and Mr. Crowley in a recreation of an Ozzfest venue. Which is all well and good, but really, it's no Bark At The Moon. Ozzy Osbourne dishes on 'Guitar Hero' and technology [USA Today]
