Of course Dio is a better singer technically but I think there is something alot of people like about Ozzy's voice. It's a really unique voice.. I mean who else sounds like Ozzy? Plus I don't think Sabbath should be called Sabbath without Ozzy...
Saw them play this live on the Damnation Tour. Mike made a comment saying this was the "Best Song He's Ever Heard Including Any Of Their Own Songs", or something along those lines. I'd have to disagree, but it's a very good song & they do/did cover it very well.
Man that tour was awesome. 'Hope Leaves', 'Face of Melinda' & 'Benighted' were so very good!
