I'd love to see Sabbath do a reunion "Live Evil" with Dio. That would freakin' rock! Heaven and Hell and Mob Rules are some of Sabbath's best work. Saw Sabbath reunion in '98 @ Skydome (Pantera opened..awesome!) and it is one of the best shows I have ever heard. They were super tight. Ozzie was a bit of an eejit theatrically but the band rocked.
