Community Music Center of San Francisco Presents: A Scene from Falke, with Prince Orlofsky's permission, is orchestrating a ball as a way of getting revenge on Eisenstein. The previous winter, Eisenstein had abandoned a drunken Falke dressed as a bat (and thus explaining the opera's title) in the center of town, exposing him to ridicule the next day. As part of his scheme, Falke has invited Frank, Adele, and Rosalinde to the ball as well. Rosalinde pretends to be a Hungarian countess, Eisenstein goes by the name "Marquis Renard," Frank is "Chevalier Chagrin," and Adele pretends she is an actress. As the night proceeds, everyone at the party celebrates the qualities of champagne.
