I thought this was going to be about gladrags.

Oh, no. Just the living and slithering variant.

Interesting concept of using an anagram of a song for a parody! Is this a "short" version of the song? Seems like a fragment. But a good one. I have some Hebrew books (non-Biblical) that deal with the serpent in the Garden of Eden and how it was a mammal that walked on its hind legs- highest in God's animal creation with the ability to speak due to it eating from the Tree of the Knowledge of Good & Evil (as opposed to some church views that Lucifer/Halel possessed it and spoke through it). The material I have describes the beast as having a shiny coat that when exposed to sunlight gave off all the colors of the rainbow, like a prism. This perhaps matches the Rainbow Snake of Australia with the Abos. It looks sorta like a Kangaroo but with longer arms 4-omnidirectional ears, and a large hood. Normal eyes and horns on its head. I find it fascinating to think about. During WW2 the LW had a concept for a "Sky Serpent" weapon that would be dropped by Messers and Fockes above the bomber stream to seek them out and destroy them. They had no propulsion system but would use the air and a chemical coating to reaction "slither" across the sky and locate the B-17 or 24 engines through acoustic sensors, detonating within proxity. Big myth that the Germans did not have proximity fuses during WW2; actually, they had 100s of types not meant for artillery but SAMs. That's why they were delayed. The USAF has its modern version which are "Filo-Flyers" (still in development). TMI, but FYI...

@Rob This and other posts indicate your historical knowledge of weaponry and aeronautic technology blows my mind. Are you a retired military man or clandestine arms dealer, by any chance, or both?

Yup, that is the single version of the song. The LP version is 24 (!) minutes. I was on Kraftwerk gig in Helsinki a couple of years ago, and - yes - that was arranged at the old Helsinki gasworks and powerplant. A fitting milieu!
