Gian Franco Reverberi (born in 1934 in Genoa, Italy) is an Italian composer and musician. He worked mainly on the soundtracks for Spaghetti Westerns.
He was one of the first Italian rock music artists. He also worked with his brother Gian Piero Reverberi on the song "Last Man Standing" (or "Nel Cimitero di Tucson") from the soundtrack of Django, Prepare a Coffin (Preparati la bara!) (one of many unofficial sequels to Django), which forms the basis of Gnarls Barkley's hit "Crazy". Both brothers are listed as writers of the song.
He also worked with Enzo Jannacci and Giorgio Gaber.
