"Mireille" (1865) was a moderate success, and although it did not emulate "Faust" in becoming an international hit, it remained popular in France into the 20th century. The most famous number, the waltz-song "O légère hirondelle", a favourite display piece for many coloratura sopranos, was written to order for the prima-donna of the Théâtre Lyrique a year after the premiere. Another popular number is Ourrias's swaggering "Si les filles d'Arles" described by the critic Patrick O'Connor as an attempt by the composer to repeat the success of Méphistophélès' "Veau d'or" from "Faust". Gounod revised the work, even giving it a happy ending, but in the 1930s Reynaldo Hahn and Henri Büsser prepared a new edition for the Opéra-Comique, restoring the work to its original tragic five acts.
