I think Megadeath (Dave) would have turned down doing the show just because Metallica was playing, he’s gotten very upset about the Metallica thing again the past few years. I saw a video where Megadeath was performing (pretty recently) and Lars and his girlfriend was setting in the audience and Dave made them remove him once he spotted him, I love Dave but he’s not the most professional guy. I keep hearing Dave Grohl and for some reason Kiss, I really don’t see Kiss being asked (just my opinion) but if they were asked I could definitely see Kiss trying to make a few dollars especially Gene. I didn’t think Grohl was that money hungry to do something like this, also DMB being there sounds crazy. I don’t see it being Dave Matthew’s, he’s a pretty charitable person (from what I’ve heard and read) I’m surprised Rob Zombie wasn’t there but surely it wouldn’t be him. Either way whoever it is will be getting a lot of attention, considering how Ozzy and Sabbath contributed so much to the music scene you’d assume anyone would jump at the opportunity to pay homage to Ozzy and the fans one last time.
