I noted in the previous post--on William Safire's speech for Nixon in case the moon landing ended in deaths--that all kinds of wonderful and strange esoterica will be revisited in the days ahead. Here's another: It seems that Pink Floyd was in a BBC studio in London "jamming" live to the first moon walk. This "soundtrack" was missing for years, then bootlegged, before finally ending up, where else, on YouTube. Here it is below. Evidently it is not the precise footage they were "jamming" to, as some of it seems to come from a later moonwalk.
Also see some of my other Armstrong coverage: 1) NBC announces the passing as that of "Astronaut Neil Young." 2) When Armstrong was on the way to the moon, the NYT corrected a story from 1920--when it mocked science pioneer Robert Goddard for claiming we could send a rocket into space some day.
