Caselli's version was a massive success, in spite of her being almost unknown at the time, and peaked at the first place on the Italian hit parade for several weeks.[3] It is considered as the song which consecrated Caselli to fame.[1][4] Caselli also recorded a French-language ("Baisse un peu la radio") and a Spanish-language version ("Ninguno me puede juzgar") of the song. Gene Pitney's version peaked at the eight place on the Italian charts.[3] It became a regional hit in the US and Australia in areas with large Italian communities.
The lyrics are about the confession of a betrayal and an unapologetic proposal of reconciliation. They were seen as an anticipation of the moral revolution and feminist themes which exploded a few years later.[1]
The song had been previously intended to be performed by Adriano Celentano, who also recorded a demo but eventually preferred to compete in the festival with his own song "Il ragazzo della via Gluck".[1]
