Here is a song from the movie "The High And The Mighty", whistled by one of the world's greatest whistlers, Muzzy Marcellino (only second to Fred Lowery, the blind whistler).
Born in 1912, bandleader Muzzy Marcellino studied both violin and guitar while growing up in his hometown of San Francisco. Between 1932 and 1938 he worked with several outfits, including the Lofner-Harris Orchestra and Ted Fio Rito's group, where he was often heard on vocals. In 1938 he formed his own orchestra, which debuted at Topsy's Restaurant in San Francisco and featured a young Gloria DeHaven on vocals. He spent the next ten years playing West Coast venues, finally disbanding his group in 1948. He then settled in Los Angeles, where he continued playing with small combos. From 1950 through 1969 Marcellino was musical director for Art Linkletter's various television programs. He was also an accomplished whistler. His whistling was featured in many advertisements and movies (he dubbed John Wayne's whistling in "The High and the Mighty", 1954, and provided the ululating whistled sting in Hugo Montenegro’s popular rendition of the theme to "The Good, The Bad, and The Ugly", 1966; he also helped with many musical numbers for the original "Mickey Mouse Club") and on several recordings. Muzzy Marcellino died in 1997.
Enjoy Muzzy's great whistling!
