The original song, whose French title means "My Beautiful Friend", features a French lyric line: "Apres Tous les beaux jours je te dis merci merci" ("After all the beautiful days, I say thank you, thank you").

The song is dominated by electric organ, and has drums, bass and acoustic guitar, with handclaps in the bridge section.

Jerry Ross, who was in Europe in the autumn of 1969 looking for European hits for release in the United States, happened to hear the song while in a club in Switzerland and he then signed Tee-Set.

This video version appears the same as the hit US rendering, but for minor differences to the repeated chorus ending.
