I enjoyed it too because Dio does not seem defensive at all; just forthright. He's a lot more informative than any of Ozzy's elusive tactics could ever go with me as a serious fan of Black Sabbath and I'm sure worst things have been said about him, but then again; I don't mind hearing it straight from the horse's mouth. Dio was there too and cannot be easily dismissed or forgotten. No matter what the tragedy, the music must evolve and that's exactly what happened with Black Sabbath.
The best thing is a fairly gentle climate - never too hot and never too cold. Clean fresh air and no crowds.
