I was on Ozzfest tour with Slipknot in 2001. I was back stage at the Wisconsin show. The first show I jumped on to the tour. Standing back stage with my friend Paul and we were talking to a guy I thought was an old roadie for about a half hour. We all shook hands and Paul went to the pre show meeting for bands but he looked at me and said, How cool is it that you can just sit here and talk to the drummer from Black Sabbath. I was talking to Bill Ward the whole freakin time and didn't know. He aged so much I didn't recognize him. Pre Cell phone so I have no pics to prove it.
