An unreleased track by Michel Berger has emerged, 23 years after the death of the French singer
The song Un dimanche au bord de l'eau was broadcast on French radio station RTL on Monday.
It dates from sessions in Los Angeles in the early 1980s, and was originally intended for his Beauséjour or Beaurivage albums, but it never saw the light of day.
Berger's widow France Gall mixed the song earlier this year, and added some of her vocals to the song.
The track will feature in the new stage musical Résiste, a show due to begin next month by Gall, one of the best known interpreters of his work.
Gall aims to do for her and Bergers' work what Mama Mia did for Abba, setting the music in a whole new context and bringing it to a new generation.
A single Les accidents d'amour by Léa Deleau was released at the end of September.
Résiste is staged at the Palais des Sports de Paris from November 4, before touring France from January 9 2016.
