Johann Strauss is a little chipper for me, but I do like this operetta "Der Zigeunerbaron", which trnslates as "The Gypsy Baron". Here is a quickie Wikipedia Overview:
Overview: This is the colourful story of the marriage of a landowner (returned from exile) and a gypsy girl who is revealed as the daughter of a Turkish Pasha, and the rightful owner of a hidden treasure. It involves a fortune-telling Romany Queen, an absurdly self-important Mayor, a rascally Commissioner, a Military Governor, a band of Gypsies and a troop of Hussars.
I like the craziness of the storyline.
