The double title was chosen by Celentano to emphasize that both songs, which had been hugely successful as the A and B sides of the corresponding single and which became two iconic songs in his repertoire, both deserved to title the album.[4] It is the last Celentano's studio album to include Don Backy's songs.[4]
