Don Giovanni
Legend says the performance in Vienna ended with Don Giovanni going to Hell. The final scene for Anna, Elvira, Zerlina, Ottavio, Masetto, and Leporello was probably cut. Mozart wrote some new music for the Vienna performance. He may have had to cut the last scene to keep the performance within a certain length of time. The opera was not as successful in Vienna as it was in Prague. It was dropped at the Burgtheater after fifteen performances.
