During a late night BBC broadcast on the night of the Apollo 11 Moon landing, Pink Floyd improvised a jam in between coverage of the event. It was called "Moonhead." It wasn't planned, just something that kind of happened. Rather fitting that the band that brought us "Dark Side of the Moon" also provided a sort of soundtrack to such a landmark event.
David Gilmour reflected in the British publication, The Guardian:
"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. 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. They were broadcasting the moon landing and they thought that to provide a bit of a break they would show us jamming. It was only about five minutes long. The song was called Moonhead — it’s a nice, atmospheric, spacey 12-bar blues."
