Although Johann Strauss the Younger was already the talk of the town in Vienna - a city where if you walked past a party or a dance, it would probably be Strauss’ joyful music that you would hear - it was not until he wrote his superb comic operetta, Die Fledermaus, that he made his breakthrough into the world of theatre.
Disguise and mistaken identity abound in Die Fledermaus. Dr Falke has been humiliated by his friend, Eisenstein: Abandoned by Eisenstein, after a drunken party, he has to make his way home, dressed as a bat, in full daylight. Eisenstein should be spending a spell in jail for breaching the peace, but Falke, giving the impression that he has forgiven him, persuades Eisenstein to go out partying again before he turns himself in. A masked ball gives Falke the perfect opportunity to exact revenge: Eisenstein and his wife Rosalinde fail to recognise each other and end up flirting, both thinking they are taking a new lover.
