Does anyone have the lyrics the song "Ansbach Dragoner" (sung to the Hohenfriedberger March)?
Two little anecdotes regarding German tunes:
It appears that in either 1945 or '46(-ish), the ceremony of the Trooping of the Colour was revived after the war. It appears that, in the haste to get the ceremony up and running, nobody had checked the music used. It is said that there were several cases of shock and appoplexy when they marched onto Horseguard's Parade to "Preussens Gloria".
A second "misplaced" use was a good few years ago when, at a Remberance Ceremony, the vicar had included the hymn "Glorious Things of Thee Are Spoken" to the tune "Austria" - better known as the post Imperial, German National Anthem ("Deutchland Uber Alles/Deutcherleid), again, there was, shall we say, a "reaction" from some of the comgregation.
