Do you remember watching The Osbournes on MTV, seeing Ozzy Osbourne piddle his way about the house, and thinking, “This guy was a rock god?” While his half-sedated state has greatly improved over the years, it actually looks like his fitness routine may finally be reaping some real benefits. Last night, the Ozzman took to the stage for an appearance on Jimmy Kimmel Live!, and the 62-year-old metal god delivered a fantastic one-two punch to the congregation of Los Angeles metal heads gathered at Kimmel’s outdoor pavilion.

Osbourne kicked off his performance with “Fearless” from his latest album, Scream, and he sounds surprisingly menacing for a man who mumbled his way to reality-TV immortality. In fact, you almost want to bow down as he sings “I answer/no questions/you will obey my order.” The music is as heavy as ever, and he even satiated the thirst of fans patiently waiting for that heavily-rumored Black Sabbath reunion by powering through a fresh version of the band’s 1980 classic, “Crazy Train”. A small circle pit ensued and further proved that when it comes to having fun at shows, trashing metalheads beat foot-tapping indie kids any day.

Check out the videos below and catch Osbourne on one of Ozzfest’s  remaining summer dates.  Tickets are still available via Ticketmaster.com.
