After a frank confession by his wife, a doctor is called to see a dying patient. The cause of the night brings him to meet an old friend, a pianist, who tells him of a mysterious ball where he is due to perform. Based on the book "Traumnovelle" ("Rhapsody: A Dream Novel") by Arthur Schnitzler, which was the inspiration for the film Eyes Wide Shut (1999).

Der Graf von Luxemburg (The Count of Luxembourg) is an operetta in three acts by Franz Lehár to a German libretto by Alfred Willner, Robert Bodanzky, and Leo Stein. A Viennese take on bohemian life in Paris at the beginning of the 20th century, the story revolves around an impoverished aristocrat and a glamorous opera singer who have entered into a sham marriage without ever seeing each other and later fall in love at first sight, unaware that they are already husband and wife.

An operetta with music by Johann Strauss II. However, he did not see the premiere. Wiener Blut is set at the time of the Congress of Vienna, 1814-1815, an international conference that sought to settle Europe after the upheavals of the Napoleonic Wars, and follows a traditional operetta plot full of mistaken identities. Count Balduin Zedlau, ambassador of the tiny court of Reuss-Schleiz-Greiz, is posted to Vienna. Count Zedlau is married but a real Don Juan always looking for a new encounter. Many of Strauss' compositions are used in the operetta although he did not specifically composed them for the operetta.
