The track was recorded during the Chet Is Back! sessions for RCA in Rome at RCA's studios in the spring of 1962. Ennio Morricone was the conductor and arranger. The choir on the session is The Swingers. The track was released as a bonus track on the Chet is Back! CD release by RCA in 2003 in the U.S. Chet Baker plays the trumpet and also sings on the track. The song was only released in Italy as a vinyl 7" 45 picture sleeve single. The lyrics are in Italian. Chet Baker composed the music. Alessandro Maffei wrote the lyrics.

In August, 1960, Chet Baker was arrested in Lucca, Italy. He was convicted of drug smuggling and forgery and sentenced to a year, seven months, and ten days in a Lucca prison. When he was released early, in December, 1961, RCA Italiana organized collaborative sessions with composer, arranger, and conductor Ennio Morricone. In 1962, they recorded four of Chet Baker's own compositions that he wrote while incarcerated: "Chetty's Lullaby", "So che ti perderò", "Il mio domani", and "Motivo su raggio di luna".
A 2012 play by Stephan Delbos used the title of the song in dramatizing the period when the song was recorded during Chet Baker's stay in Italy in the early 1960s.
