From the Wiki: “The expression “Spandau Ballet” was slang used by Allied troops in the trenches in the Second World War referring to the twitching of the corpses hanging on the barbed wire and repeatedly hit by Spandau machine gun fire from the German lines.”
I thought Spandau Ballet referred to the Nazis convicted at Nuremburg jerking & twisting at the end of the hangman’s noose since some of them didn’t die instantly when the trapdoor dropped.
Sounds kinda like the funky chicken, but that’s done whilst electrocuting.
That makes it even creepier
But there was also a band called that
