I was lucky enough to see this tour, which I thought was great. As expected, Tony Martin performed the Dio songs well, but he also did a pretty good job on the Ozzy songs.
More importantly, I remember one time back in the 90's I was playing this CD in my car as I was drying off and vacuuming my car after giving it a self serve car wash. This rather attractive and slightly older lady heard the music and really liked it and asked who it was. I actually think she was hitting on me, but I had a live in girlfriend at the time. But hey, the point is .. its a great album.
