It was a while back, but I was looking through one of those "Heaviest Riff" Threads and there was a link to a Sabbath Video, it was a Live concert with Dio, and the intro was like chug chug chug ...i cant seem to find the link or remember what song it was ...and its kinda making me mad...

its a pretty vague description but if anyone can help, it'd be awesome
