Le postillon de Lonjumeau

Le postillon de Lonjumeau (The Postillion of Lonjumeau) is an opéra-comique in three acts by Adolphe Adam to a French libretto by Adolphe de Leuven and Léon Lévy Brunswick.

The opera has become the most successful of Adam's works, and the one by which (apart from his ballet Giselle and his Christmas carol Cantique de Noël) he is best known outside his native France. The opera is known for the difficult aria "Mes amis, écoutez l'histoire" which has been called a test for tenors because of the demanding high D, or D5, at the end of the aria.
