Oh dear. So not only is Ozzy Osbourne in a World of Warcraft commercial, but he’s also going to close out next week’s Blizzcon with a rock-n-roll concert. Break out your lighter Apps!

Blizzard’s CEO, Mike “Money Bags” Morhaime, said:

Our goal with BlizzCon is to deliver an unforgettable weekend of entertainment, and we can’t think of a better way to close out this year’s show than having Ozzy rock the house.

Indeed. I don’t know how much the World of Warcraft audience overlaps with Black Sabbath fans, but it could well be fun.

Longtime CrunchGear readers will remember Ozzy performing in Times Square for the launch of Madden in 2007. I met comedians Jim Norton and Jim Florentine that day. It was the happiest day of my life pretty much.
