Although I am a Dio years fan and not Ozzy I did got to see Sabbath with Ozzy as it had to be done, also I have been to the Ozzfest to see him too. I like his guitarest Zk Wylde and think he is a great player !! I love one of Zaks solo songs called Horse called War, what a riff, love playing that !! Oh and the one time I went to see sabbath with Dio as singer, when we got there at the hall, it was cancelled due to floor stage problems, we were gutted. We got a refund and bought tickets to see Thunder the week after. But Dio stayed on and met us to say sorry and autographed stuff for us.
