Rheinberger, Josef’s “Singspiel”, based on Wilhelm Hauff’s fairy tale ”Kalif Storch,” has an oriental flavour: Through a magic trick the Caliph and the Great Vizier of Baghdad have been transformed into storks. Only a magic word can change them back to their original form, but unfortunately they cannot remember it …Can the night owl rescue them? This story of the Caliph, the cloth merchant and the animals, interpreted by the Children’s Choir of the Stuttgart State Opera, directed by Knecht, Johannes, offers exciting musical entertainment for adults as well as children.
