Agatha and the Midnight Murders

In an earlier review, djalloyingj-7365929 August 2021 asks how a film set in 1940 can have a rude song about Hitler's balls set to "The Bridge on the River Kwai" march theme, when "The Bridge on the River Kwai" was made many years after 1940 and the end of World War II. What djalloyingj-7365929 does not realise is that the march theme used in "The Bridge on the River Kwai" is actually a much earlier military march, written by a British counterpart to America's military march king, John Philip Sousa. The original march is called "Colonel Bogey", and a little web-searching can add much detail to this, although "Colonel Bogey" seems to be a fictitious character. The naughty words, very popular with the British army, and naughty little boys, tell us that "Hitler had only one brass ball, Goering had two, but very small, Himmler was somewhat sim'lar, but poor old Goebels had no balls at all!" This may not have been historically correct, but was very satisfying to sing very loudly. The idea that Agatha Christie, in real life, might find herself in a real murder scene, and be able to use her fictionally honed mystery-solving skills to solve the mystery is sufficient to motivate "Agatha and the Midnight Murders", and other (fictional) murder mysteries that do not involve Christie's usual sleuths, such as Poirot and Marple.
