Man with Harmonica - Once upon a time in the west

This is the music from the movie "Once Upon A Time In The West". The title of the theme is "Man with Harmonica".
The song is made by Ennio Morricone, who is known by themes as "The untouchables", "The good, the bad and the ugly", "For a few dollars more" and "A fistful of Dollars".
This is one of the better movie themes, and it`s also one of my favorites
