It was Live 8 when I realized it.
Somehow Ser Bob Geldof had talked Roger Waters, David Gilmour, Richard Wright and Nick Mason into to playing together for the first time in over two decades — shaking off or at least ignoring the humongous well of bad feelings that had accumulated in all of that time. It kinda felt like a miracle watching them. So after the requisite pair of songs from The Dark Side of The Moon, backup guitarist Tim Renwick starts playing the tinny guitar from the opening of “Wish You Were Here” — the conceit on the album being that someone is listening to “Have a Cigar” on the radio, wants to hear something else and while scanning the dial, lands upon “Wish You Were Here” (tough luck Pink Floyd Haters) — and Roger Waters addresses the crowd, because even he is caught up in the weirdness.
It’s pretty short, of course, but he talks about how much emotion playing with the other guys is raising inside of him, and dedicates “Wish You Were Here” to “Everyone who’s not here. Particularly, of course, for Syd.” Of course.
