[1] As for the previous three singles from the album, "Joue pas", "Les Valses de Vienne" and "C'est toi qui m'as fait", it had a great success in France, reaching the top of the SNEP chart, thus becoming Feldman's second number one hit.

As for the previous singles from the album Une Présence, "Petit Frank" was written by Jean-Marie Moreau, while the music was composed by François Feldman himself.

According to Elia Habib, an expert of French charts, the song enjoys a "genuine sensitivity" and its "main character is a boy, abandoned or orphaned, presumably placed at the Assistance publique - Hôpitaux de Paris, faltering between combativeness and vulnerability".

The black and white music video illustrating the song shows the young boy Frank, played by French actor Boris Roatta, tormented by his schoolmates who do not understand his suffering.
