Umberto Antonio Tozzi (pronounced [umˈbɛrto anˈtɔːnjo ˈtɔttsi]; born 4 March 1952) is an Italian pop and rock singer and songwriter.
In 1974, Tozzi had his first success as a songwriter, with the song "Un Corpo, un'anima" ("One Body, One Soul"), co-written with Damiano Dattoli and performed by Wess and Dori Ghezzi.
In 1976, he released his first album, Donna Amante Mia ("Woman, My Lover"), which contained the single "Io Camminerò" ("I Will Walk"), which was sung with great success by Fausto Leali.
Branigan worked with the arranger and keyboardist of Tozzi's own version, Greg Mathieson, to give the song what she called "an American kick.
In the 1990s, Tozzi recorded several more songs such as "Gli Altri Siamo Noi" ("We Are the Others"), the album Equivocando ("Misunderstanding"), Il Grido ("The Outcry") and Aria e Cielo ("Air and Sky").
In 2013, his re-edited version of "Gloria", sung in its original Italian, was placed by Martin Scorsese onto the soundtrack of the 2014 Academy Award nominated blockbuster, The Wolf of Wall Street.
