This is just what they want you to believe. A fluff piece on Livescience.com has reported that the sounds, the music, the members of Apollo 10 heard while wandering around on the surface of the moon, was nothing more than static between the command vehicle and the ground vehicle. The VHF radios were acting up.
Well I was in communications in the Army and I don't know anything about VHF radios, so that might be true.
But it seems might convenient.
Actually the fluff piece is a fairly written piece, but not all believe the sounds were from the VHF radios. Al Worden, from Apollo 15, doesn't believe. Something else it as play...or so he says.
