Numéro un (Number 1) is a variety show that aired in France from 1975 to 1982.
The Sesame Street Muppets Big Bird, Ernie, Bert, and Oscar the Grouch made an appearance on the March 26, 1977 episode hosted by Mireille Mathieu. Mathieu argued with Oscar, was surprised at the size of "canary" Big Bird, and sang a rousing "Tous Les Enfants Chantent Avec Moi" ("All the Children Sing with Me") accompanied by Ernie playing the piano and Bert strumming the guitar. While Big Bird danced with her, even Oscar joined in on singing the song.
The Sesame Street Muppets' voices were dubbed by Jacques Deschamps, Philippe Dumat (Ernie), Henri Djanick (Bert), and Serge Lhorca.
