If you ask me i'd rather hear the songs dropped than a couple of the songs actually played. If i see this is gonna be the same set as the Ozzfest at the O2 i'm not going. If i see he starts to play regurlarly Killer Of Giants, No More Tears and Fearless i'll go, simple as that.
Come on Ozzy! we all wanna hear Killer Of Giants!! as for No More Tears being difficult for you to sing now, well, get ready during the solos, have one of those hot Tea singers drink to help the voice and sing it right after the solos are done.
It would also be fantastic to hear others great songs which haven't been played for ages such as Miracle Man and Perry Mason
