Les p'tites Michu (The Little Michus) is an opérette in three acts, with music by André Messager and words by Albert Vanloo and Georges Duval. The piece is set in Paris in the years following the French Revolution and depicts the complications ensuing after the identities of two girls become confused in their infancy.

The opera opened at the Théâtre des Bouffes-Parisiens, Paris, on 16 November 1897 and ran for more than 150 performances. It became an international success, with productions in four continents, including an unusually long run of 400 performances in London, and had subsequent revivals in Paris.

After a considerable success in 1890 with his opéra comique La Basoche Messager had a series of failures later in the decade. Among these, Madame Chrysanthème (1893) played for 16 performances in Paris,^[1] Mirette (1894), written for London, had a disappointing run, and Le chevalier d'Harmental (1896) ran for only six performances at the Opéra-Comique.^[2] An opérette, La fiancée en loterie (1896), managed 71 showings,^[3] and a "pièce fantastique", La montagne enchantée (1897), closed after 35 performances.^[4] Discouraged by these failures, Messager resolved to compose no more, and retreated to a cottage in the English countryside with his wife, the Irish songwriter Hope Temple.^[5] In 1897 he received an unsolicited libretto. He did not know at the time that three other composers had already turned it down, and it appealed to him greatly. He began composing and completed the score in three months.^[6]

The first performance was at the Théâtre des Bouffes-Parisiens on 16 November 1897, starring Odette Dulac in one of the title roles, with the production running for over 150 performances.^[7]

In 1793, the wife of the Marquis des Ifs dies in childbirth. The Marquis, before disappearing to evade arrest by revolutionary forces, entrusts the infant girl to the Michus, paying the family a sum of money that allows them to open a prosperous shop. The Michus have a daughter of their own. While bathing the two babies, M. Michu mixes them up and cannot tell which is which.

Act 1

By 1810, the girls, Blanche-Marie and Marie-Blanche, have grown up together, believing themselves to be twins, and have gone to school under the military Mlle. Herpin. Aristide, the Michus' clerk, is in love with one of the girls but is not sure which. The Marquis des Ifs, now a general, sends Bagnolet to find his daughter, whose hand he has promised to lieutenant Gaston Rigaud, an officer who saved his life. It turns out that Gaston is Mlle. Herpin's nephew, and while visiting his aunt, the girls meet the handsome lieutenant, and both are enchanted. Bagnolet finds the Michus. They are embarrassed at being unable to say which of the girls is the general's daughter.

Act 2 The general and his guests await the arrival of his daughter. When the Michus arrive, the general is impatient with their explanation: he wants to know which girl is his daughter and will marry the lieutenant. Knowing that her sister is enamoured of Gaston, Blanche-Marie decides to make a sacrifice and identifies her sister as the general's daughter.

Act 3

With a sad heart, Blanche-Marie resigns herself to marry Aristide, whom she finds exceedingly uninteresting. On the other hand, and to the astonishment of her fiancé and the Marquis, Marie-Blanche goes to help at the shop at every opportunity. She realizes that she has made a mistake: her sister loves Gaston, and she herself would prefer the common life of the shop and marriage to Aristide. The day of the double wedding, Marie-Blanche looks for a portrait of the Marquis' wife. Her idea is to dress Blanche-Marie as the late Marchionesse. The resemblance is astonishing. The Marquis believes that he sees his wife: Blanche-Marie must be his daughter.

The two couples are sorted out and all ends happily. Madame Michu forbids her husband to hand the two young women to their respective bridgrooms: "Don't you touch them, or you'll mix them up again!" ^{[n 1]}
