Das kleine Hofkonzert (The Little Court Concert) is a musical comedy in three acts (ten scenes) "from the world of Carl Spitzweg", music by Edmund Nick, libretto by Paul Verhoeven and Toni Impekoven.
Her only clue is the song "When the evening's dark veil..." ("Wenn des Abends dunkler Schleier...") which her mother sang 25 years ago for this man.
Walter, son of Earl Marshal von Arnegg, has immediately fallen in love with Christine.
His Serene Highness, learning that his concert has to be cancelled because Christine has been driven out of town, recalls her.
She also mentions her mother's song, and the old man remembers his affair with a handsome singer 25 years ago.
