Maybe ( ) but did he ever quit smoking? Dude was a chimney!
Just saw this post of yours - I was "catching up" on some of your music posts (love them!) I just watched a great documentary on Keith on Netflix. One thing I learned is that he married Patti Hansen in 1983, and they're still married. Kind of rare for a rock star like him to be married only once. Same thing with Charlie Watts. He married Shirley Ann Shepherd in 1964, and they stayed married right up until his death last month.
