This is a bit sad to see. I understand the applause - the passion and the spontaneity and the energy are still there. But to me it sounds like the time feel and the touch have gone.
Seeing a lot of this now with aging rockers. Time is a cruel mistress, etc.
Have to say, though, I saw Gilmour a couple of years ago and his playing was perfection. Luck of the draw, I guess.
