Radiodiffusion-Télévision Française (RTF) aired Sept villes, une chanson on its television channel every two weeks on Fridays between 21 December 1956 and 28 February 1957 at 20:40 CET.

[4] The winning song "Le Petit Homme et la noix" was written by Henri Bourtayre, with lyrics by Francis Blanche.

[6][7] As the interval act, Jacqueline Roland performed the winning song from heat 1, "Le Petit Homme et la noix".

[6] The spokespersons of the following juries in Lyon and Nice protested against this irregularity before giving their respective votes, wrongly accusing Marseille instead of Lille.

[3] It was in this heat that Robert Beauvais announced for the first time that the show would serve as the selection for the French entry in the upcoming Eurovision Song Contest.

[7][17] John Littleton [fr] performed the winning song from heat 2, "Le Manteau de laine", as the interval act.

[8] The winning song from heat 3, "C'est demain" was played by Joss Baselli [fr] and Paul Durand's orchestra in an instrumental version as the interval act.

[37] On 21 February, Deutsches Fernsehen published a press release on the upcoming contest in Frankfurt, saying that Paule Desjardins would sing a song by Guy Lafarge for France.

[40][41] Official TV listings for the Eurovision Song Contest on 3 March still claimed that the French entry had been chosen in Sept villes, une chanson.

[42] Apparently, RTF did not inform television viewers sufficiently ahead of the Eurovision Song Contest: TV listings magazine Télévision Programme Magazine later reported having received numerous letters by angry viewers who criticised RTF for its lack of transparency in the selection and for the last-minute replacement of Josette Privat (who had sung the song in Sept villes, une chanson) with Paule Desjardins.

[45] Eurovision Song Contest 1957 was broadcast on French television RTF and radio Paris-Inter, on both stations with commentary by Robert Beauvais.
