I was too young to witness this myself, but my understanding is VH pretty much dominated that tour.. I have a bit of info for you diehard guitar fanatics. I don't know if you are aware of this or not, but check this out..Regarding the BS and Van Halen tour....At most arena rock concerts that you see there are usually a wall of guitar amps onstage , but only one or two are actually turned on. They mike one of the ampcabinets and the sound is then pumped through the PA speakers above the stage. But, TOny Iommi used to actually use ALL of the amps onstage and he hardly needed to be mixed into the PA at all cause he was so loud onstage.. Eddie loved the way this sounded when VH was touring with Black Sabbath and he started doing the same thing for many years afterward. Inm fact, if you read old VH interviews Eddie often makes the comment that it is so loud on his side of the stage that MIke and Dave dont even come over to where he is.. Now you know why..

..Also there is a great story in david Lee roth's book Crazy from The Heat about how Ozzy got left behind in one of the cities on the tour and the dudes from sabbath asked dave if he could sing for them that night, but he , unfortunatley , did not know any of thier lyrics...Can you imgaine if it acutally happened even for one show..DAVID LEE ROTH singing BLACK SABBATH songs with Sabbath for two hours..I would pay top dollar for that shit.. wouldnt his "Look at all the people here tonight" raps be kind of funny at a Sabbath show?
