Dude, that sucks, I was just thinking about him all week.
I had no idea, but for some reason I picked up the guitar a couple days ago and could not seem to play anything but DIO tunes, than I popped in a couple DIO cd's and listened to him all night.
I'm bummed....I had no idea he was dying, must have been the DIO vibes.
My greatest rock hero of all time.
