Also, about Crosby, Nelson and MacGowan:
Comparing them, Crosby seems to be the only one who actually writes his social media posts.
However Crosby had one year to live (according to himself) in 2019. He has used cocaine, heroin and everything, got a liver transplant in 1994 (funded by Phil Collins, who is also quite deathlisty now) has diabetes and his heart is probably going to explode soon. On the other hand he's planning on performing in June 2022 according to ticketmaster.
Nelson still performs and releases music but it's now 40 years since his lung collapsed, used to smoke two to three packs of cigarettes a day before that, had pneumonia multiple times decades ago, repeated instances of pneumonia and emphysema in the 2010s. Currently looks like he'll make it to 90 (April 2023) but who knows. Kris Kristofferson is much more quiet than Willie nowadays, which one will ride off into the sunset first?
MacGowan is only 63 and his dad is still alive but he's a former heroin addict and has been drinking for decades. In a wheelchair since 2015 and looks very frail, had a serious bout with pneumonia around 2015 or 2016 and was hospitalised around January. Arguably in a much worse condition than most of the people on the list. Could go on for a couple of years but I can't imagine him living to 70, even 65 would be impressive.
