The music to the UK national anthem was, prior to German unification in 1870, the theme of the Prussian R. family. I am awaiting an opportunity to sing the true lyrics in the presence of the Wh0re of Windsor or one of her foul clan... "
Heil dir im Siegerkranz..."
I beleive the tune is also still used for the national anthem in Lichtenstein and, at one time, Switzerland.
In a similar vein the anthem of the socialist movement, "Keep the Red Flag Flying Here" tends to have Americans bursting into choruses of "Oh Christmas Tree", and isn't "Land of Hope and Glory" know in the US as "The Graduation Song"?
BTW: Isn't that a well-groomed version of Andy D1ck in the video?
