The noise to me anyway sounded a bit different from the noise near Saturn which were charged particles coming in contact with Saturns' magnetic field. Ther moon of course has no magnetic field.

Just saw the program and the segment on the "music" heard. It was very creepy to be sure! It reminded me of a high wind whine noise. Very very eerie. Unfortunately the program has not been posted yet on the Science Channels website, so I cannot include it yet. But the possible vhf comm link was poo pooed by an astronaut spokesperson who said " the astronauts would know what they should expect to hear and what they would not expect to hear", and this would be one of them.

Is it possible that the VHF feedback interference would sound different since they were on the far side of the Moon? Don't forget, their VHF radios would have been shielded from any other background noise or background interference that you are accustomed to on Earth, which would have made the feedback interference pure.
So could that pure interference (lacking any of the other background noise from Earth) sound odd due to being so pure?

So who was outside over the far side of the Moon when there was nothing else from here up there? Yes I checked, nothing from NASA and the Soviet missions had either blown up on take off or failed to make stable Earth orbit before setting off for the Moon.
"Who" not "what". I find it hard to come up with an explanation for that comment which doesn't involve alien spacecraft.

To make sure -- you do realize from the LM, the CM was flying free outside?

There is no question that they heard these sounds. The question is, "what was the cause?".
I would say it's not "a bunch of horse manure" in as much as that they DID IN FACT hear eerie whooshing and whistling sounds over the radio which was caused (as per the one of the possible explanations, one which seems plausible) by VHF feedback interference from the radios of the two spacecraft.
You can get some interesting sounding noise out of various sources. I had a tape I'd made out of RF noise coming from an old four-banger calculator, it was quite musical and interesting.
Had one of those creepy moments once when we were (for odd and confusing reasons) trying to measure domain noise on a big magnet, I decided it might be useful to listen to it, put a tape head in the field and hooked an amp to it. The magnet was putting off this sound like wind blowing through a canyon, complete with whistling noises.

Space is a vacuum, the purest way that sound travels. Without any loss.
This sound is probably some sort of harmonic that is enjoying the pure atmospheric conditions. Radios in that era could even have had vacuum tubes (very high fidelity) but they can produce noise (and heat).
