Violet of Montmartre

The operetta, "Das Veilchen vom Montmartre" (Violet of Montmartre) by Emmerich Kálmán sometimes, but not always, includes a cancan.  Not often performed in the US at least, it seems to be the most popular in Russia where the translated title is "Фиалка Монмартра".  Naturally, that results in a lot of split skirt versions.  The musical number that includes the cancan is "Carambolina".
