The whistling in the film “The Man with No Name”
(also known as “A Fistful of Dollars”) was performed
by Alessandro Alessandroni.
He was an Italian whistler and singer who contributed to many film scores, especially in the Spaghetti Western genre.
The film’s composer was Ennio Morricone, but the main theme was supplied by his friend Alessandro Alessandroni, who also played guitar on the soundtrack.
Alessandroni, who died aged ninety-two, was the expert whistler on several of film-maker Sergio Leone’s Spaghetti Westerns, notably on “A Fistful of Dollars”.
