If you haven't watched it yet, here it is. Jack Black doing a cover of Ozzy Osbourne's "Mr. Crowley" for Tom Morello from Rage Against the Machine's mom's 100th birthday. The really cool part about this is that his backing band was a bunch of 12 and 13-year-olds, including Tom's own son, Roman Morello. Who, as you'll see in the video, obviously is a chip off the ol' block.
