A stage musical based on the film was produced in France in 2003, adapted by Alain Boublil and directed by Daniel Moyne.

Étienne and Bill, two carnival workers who sell motorcycles, bicycles, and boats, help set up, while, in an apartment, Delphine teaches ballet to a group of children and her fraternal twin sister, Solange, accompanies the dancers on piano.

The twins live in Rochefort, but long to find their ideal loves and move to Paris, Delphine to dance and Solange to compose.

Solange goes to see Simon Dame at his music shop to ask him to arrange an introduction to his old friend, successful American composer Andy Miller, who is currently doing a series of recitals in Paris.

Later, Yvonne tells Maxence the story of her relationship with the father of her young son, Booboo, indicating she regrets leaving the man just because she did not want to become "Madame Dame".

He tells Solange to go to his shop to see Andy, who is unexpectedly back in town for a short time, and agrees to pick up Booboo from school so she can do so.

English-speaking Canadian singer Don Burke recorded Kelly's vocal parts, singing in French with an American accent.

The site's critical consensus reads, "The Young Girls of Rochefort pays colorful homage to classic Hollywood musicals while earning its own emotionally affecting place of honor in the genre."

"[11] Similarly, in 2022 David Ehrlich of IndieWire named it the 34th greatest movie musical of all time, deeming it, "A sneakily bittersweet masterpiece," and comparing it favorably to Demy's previous film, The Umbrellas of Cherbourg.
