In the demo version of Kartemquin Films' series on the lives of new U.S. immigrants, The New Americans, Israel Nwidor whistled along with a George Strait song. The Filmmakers claimed fair use.
Kartemquin invoked fair use because Israel spontaneously chose the music and whistled in a scene whose purpose was to show his daily life as a new immigrant. The filmmakers did not use the music as a soundtrack element.
