Monsieur et Madame Denis is a one-act opéra comique with music by Jacques Offenbach to a French libretto by Laurencin (Paul-Aimé Chapelle) and Michel Delaporte, first performed in 1862.[1] The work was based on a popular vaudeville, and included a ‘chaconne’ (also quoted in the overture) which became well known in its own right.
