I don't even know if I'll be going to that. I missed their first tour which I still regret, but I caught them with Priest, and they were good.
Once might be enough for me, since it just doesn't do as much for me as the original Sabbath. If you factor in that they'll be playing a bunch of songs I don't want to hear, it's a no go.
