The song realistically recounts in dialogue form the meeting of two ex-lovers and the rekindling of their passion.

[1] It was composed during a journey in the United States, while travelling in a car on Interstate 5, and had the working title "San Diego Freeway".

[1] Ernesto Assante wrote about it: '[it's] difficult to search for verses, refrains, bridges, in a marvellous broken and danceable rhythm in which funky and disco are so sophisticated and elegant as to seem elusive, and the melody evolves in a crescendo that allows Battisti to sing at his best, up to his by then classical falsetto'.

Artists who covered the song include Mina, Marcella Bella, Paola Turci, Formula 3, Jack Savoretti, Róisín Murphy, T. Storm Hunter, Cristiano Malgioglio with Maria Schneider, Tiziana Rivale.

[3][4][5] It was sampled by Sangue Misto in "Manca Mone" and by Dargen D'Amico in "Bere una cosa".
