Marinka is an operetta by Hungarian composer Emmerich Kálmán with book by George Marion, Jr. and Karl Farkas, and lyrics by George Marion, Jr. The operetta is a retelling of the story of the Mayerling Incident, but with a happy ending replacing the infamous 1889 double suicide of Austrian Crown Prince Rudolf and his mistress, Maria Vetsera. The best-known songs include "Only One Touch of Vienna," "Sigh by Night," "The Cab Song," and "When I Auditioned for the Harem of the Shah".
