The melody of the song was composed by Roby Facchinetti with the intent of being performed chorally by all members of the group.[1] The lyric theme go against the will of their producer and their record company, as it deals with social criticism about the story of a man unjustly imprisoned.[1] The tensions between the producer Giancarlo Lucariello and the drummer-lyricist Valerio Negrini, eventually led the latter to leave the group (even if keeping on collaborating with them as lyricist) and being replaced by Stefano D'Orazio.[1]
The single was released on 28 September 1971 and it was the second Pooh single in a row to top the Italian hit parade.[1] It sold over 850,000 copies.[2][3]
Pooh also recorded the song in Spanish as "Pensamiento".[1] In 1998, Negrini and Facchinetti sued Alanis Morissette for plagiarism of the song "Mary Jane", eventually losing the case.[1][3]
