As an aside, one of the reasons I like the Dio-led Sabbath is that after a concert in 1981 we actually met Ronnie James Dio and Black Sabbath. It was December and a stop on the Mob Rules tour here in Salisbury. We had camped out to get front row seats ($8.50).
After the concert we waited in an adjacent parking lot and watched the back door of the venue through which the band had to emerge to get to their limo. We waited 45 mins and they came out, bundled up against the cold. We jumped out of the car and ran across the verge as the band hustled to the limo. Ronnie Dio saw us and I heard him say to the others "Hold up, we have some fans" We walked up and asked the band to autograph our albums which they did. Ronnie Dio looked at us and said "I saw you guys in the front row, it looked like you really enjoyed the show" We assured him it was great and he asked if we camped out to get the tickets, We told him we did and he replied "we're honored you would do that, I hope you feel you got your money's worth tonight" I said it was well worth the money and time and Dio said if we weren't happy he's refund our money right there. He then asked "What do you do when you're not going to rock concerts?" and I told him we were students at University of Maryland. "Great! Get your degree. Regardless of what you do after that, no one can ever take that degree from you" We were awestruck that this band made time for 5 fans on a cold, windy night after a 2-hour show.
We spent 10-15 minutes talking to what was one of the most iconic rock bands ever, and they, especially Ronnie James Dio, could not have been more gracious. Dio was genuinely interested, and was very well-spoken and articulate. Years later I learned that Dio had a long history of spending a lot of time with the fans. Ronnie Dio is hall of fame in my book.
