Besides all the dope and liquor, he had bad hip problems. By the time he got sober, his health was too bad to risk hip replacements. I have long felt that if had died around the same time as Jimi and Duane, he would probably be held in the same esteem. They certainly enjoyed getting blasted as much as he, they just died before it showed up in their playing. Second Winter - the three-sided one - astonishing playing. And there was one of the Allman Brothers 2008 Beacon shows that Johnny sat in on. They made the mistake of letting him call the tunes, and he played some real hardass Texas blues, a song called "Blackjack", maybe? He friggin' torched Warren Haynes and Derek Trucks, they were not ready for the aggression. Then they carried him back offstage, grinning like a fool, no doubt.
