en Cuevana 3. The most brilliant of Austrian operettas takes us to the outskirts of romantic Old Vienna. It’s New Year Eve and we are in the company of Caroline, who is determined to teach her philandering husband Gaillardin a lesson, even while she is being pursued by her former beau, the operatic tenor Alfred. At the centre of the action is the extremely wealthy, eternally bored Prince Orlofsky, whose lavish masked ball brings everything to a most delicious boil. But what if the whole plot has been a cunning plan masterminded by someone just to get back at Eisenstein?
