On July 20, 1969, the members of Pink Floyd watched the Apollo 11 landing, too, but not like anyone else:
“[Pink Floyd] were in a BBC TV studio jamming to the landing. It was a live broadcast, and there was a panel of scientists on one side of the studio, with us on the other. I was 23,” [David] Gilmour writes in the Guardian. “The programming was a little looser in those days, and if a producer of a late-night programme felt like it, they would do something a bit off the wall. Funnily enough I’ve never really heard it since, but it is on YouTube.”
The jam was uploaded to YouTube, and it’s pretty spectacular.
