Here are four who've been looking like death-warmed-over for years:
Singer-songwriter David Crosby of CSNY - liver transplant, heart blockage
Singer-songwriter Gordon Lightfoot - aneurysm & stroke
Rolling Stone Ronnie Wood - lung cancer & declined chemo for it
Willie Nelson - breathing issues
and then there's Joni Mitchell with that aneurysm in 2015 ...
U. R. right 😥 It sounds like THE DAY THE MUSIC DIED. I am SADDENED.
