To obtain a hit in France, Mecano decided to collaborate with Pierre Grosz, a lyric writer, who had already written several songs for Elsa ("Quelque chose dans mon cœur", "Jour de neige").

This song deals with lesbianism, seen through the eyes of a friend, who does not want to pass judgment on this relationship and prefers to be tolerant.

[4] After a prestigious Iberian career, Mecano thus became the first Spanish group to reach first place in France's Singles Chart.

Argentine singers Sandra Mihanovich and Celeste Carballo notably covered the song and included it as the title track of their second and final studio album as a pop duo, Mujer contra mujer, released in October 1990 by RCA Records.

[1][9] The choice of title, cover art and songs were centered on the message of lesbian love, considered a bold and unprecedented act in Argentine popular culture.

[2][11] The song was produced by Argentine rock musician Fito Páez, who also played the piano, keyboard, bass and electronic drums.

[14][15] The duo also appeared at Imagen de Radio, a TV program hosted by Juan Alberto Badía, where Carballo famously came out in a landmark moment for Argentine lesbians.

On June 6, 2003, the song was certified Silver disc (meaning over 100,000 copies were sold) four months after its release by SNEP,[19] becoming Saya's greatest hit.
