Yeah. Sucks. They just did a story about his 70th birthday on XM Octane the other day. Talking him up how he's smoked and drank since he was about 10 years old, and how he's still kicking. The story said he went to the doctor on the day after Christmas, found out he had cancer, died 2 days after that. Amazing.
But, look at it this way, he lived life to the fullest. If he had found out last year or the year before about the cancer, he probably would have still died but he would have been thinking about it and maybe not enjoying and living life as usual.
RIP to one of the Metal Gods!
