The Threepenny Opera serves up a deliciously dark satire of “respectable” society, with dashing thieves, saucy prostitutes, and lingering melodies. Based on Elizabeth Hauptmann’s German translation of John Gay’s eighteenth-century The Beggar’s Opera, The Threepenny Opera thrusts the audience into the seedy underworld of Mack the Knife, a dapper criminal and his wry love affair with Polly Peachum.
