Les Petits Chanteurs de Saint-Marc (English: The Little Singers of Saint Marc) was a children's choir, founded in September 1986 by Nicolas Porte.
It was a mixed unit composed of seventy-five to eighty school-aged children from ten to fifteen years old.
The choir's repertoire varied widely from spiritual hymns to classical and contemporary music.
The choir held a performance, entitled Les Choristes en concert in which they sang a variety of songs, including several from the film.
After Maunier's departure from the choir, Lizé moved to first soloist and his prior spot was filled by Rabi Ramadan.
