An online review of the Peter Green tribute concert,
early 2020 at the London Palladium,
says that the concert's MC and organizer,
Mick Fleetwood, recruited Dave Gilmour to play,
amongst other things,
Part Two of Oh Well,
and later, Albatross.

And Fleetwood, according to the review,
made a point of announcing from the stage that
Oh Well Part Two
was being performed live in public
for the first time EVER.

Oh, and there were murmurings that
Peter Green agreed to attend the performance
on the condition that he be allowed to remain
private and anonymous.
So, no brief splashy acknowledgement of Green from the stage.
We'll never know, I suppose.

Green is said to have a home in South London
(Richmond?) where others look in on him, and after him;
and as long as his privacy is respected,
he is emotionally even and stable,
and mentally sharp.
Likes to go fishing and to paint.
