When I was 14 and Paranoid was released, I borrowed my grandparent's Wollensack tape deck and made a copy of it to take to the summer cabin. My grandfather was in the early stages of dementia and upon hearing the first track, he asked me "Is that a recording of a man going insane?". I thought it a hilarious question at the time. Perhaps he wasn't as far off the mark as I thought. Ozzy managed to deal with his demons and produced some of the most amazing music ever. With Sabbath he helped usher in "heavy metal". From all accounts a great man dealing as best he could with his demons. He will be greatly missed.
