The song was written and composed by Claude Lemesle.[1] He wrote it when he was just 25 and still feels a particular tenderness towards it.[2] Lemesle recalled to Le Figaro:
I wrote it when I was very young, at 25. I wrote [both] the lyrics and the music. It really resembles me. I wanted to call it "La bande à Jojo", but since Joe had already done "La bande à Bonnot", there was too much similarity between the two titles. Forty-seven years later it holds on, I still love it. It embodies the philosophy of the 1960–1970 era, but I did not realize it [back then]. It joined a song by Pierre Delanoë I adore, "Soiree de prince". Mine is more festive, it represents another mood of the [same] era.[2]
