The edited version that aired during the show served as a nice teaser for their new album, but now that Black Sabbath have finally released '13,' they're letting fans see their complete performance of the new song 'End of the Beginning' from the season finale of 'CSI.'

"I’ve watched every episode since it started," enthused Sabbath bassist and 'CSI' fan Geezer Butler in a behind-the-scenes clip. “‘Cause I like crime stuff, and it was realistic."

For singer Ozzy Osbourne, who's more accustomed to dealing with cameras thanks to his stint on 'The Osbournes,' the band's appearance was more of a job. "I’m not an actor,” he explained. “It’s like a hurry-up-and-wait. When you see it on TV, it’s all done, but when you’re filming, there’s a lot of stuff going on."

The episode originally aired May 15, but if you missed it the first time around -- or you've just been waiting for your chance to get maximum Sabbath out of television's top-rated crime procedural -- you can soak in all eight minutes and 20 seconds of the clip embedded above. (Or if you'd prefer to watch the full 'CSI' season finale, you can still stream it at the CBS site.)
