Well, it is a mysterious song, because the tune is a remarkably good one, and sounds like it has to come from an older dance tune, to which someone then wrote a military parody. It is just too good a tune to have been invented by an anonymous soldier at some anonymous time. People who invent tunes that good, in recent times, have not normally remained anonymous. And I respectfully suggest that if someone can locate the sheet music for that tune, so that we know when the tune was popular, we have the key to when the song itself originated.

Someone once told me there was a Spanish song, transl. "I Like them All." Is that a concept for anyone?
