As of now, only two of the four longest-term band members are still alive - and they can barely stand to be in the same room together.
I’d say this announcement is a case of “making the obvious official”.
?? Nick Mason, Roger Waters and David Gilmour are all still alive.
The impression that I got from any recent interviews is that any problems between Gilmour and Mason are one-sided on Gilmour’s part, mostly because of Gilmour being unwilling to do any more tours.
At first glance, I thought you meant they could barely stand up and was going to admonish you not pick on the elderly...
No ... Nick, Roger and Dave are still alive. The only one that has died is Rick Wright (discounting Syd which is ancient history)
