Song of the West is a 1930 American Pre-Code musical western film produced by Warner Bros., and photographed entirely in Technicolor. It was based on the 1928 Broadway musical Rainbow by Vincent Youmans (music), Oscar Hammerstein II (lyrics) and Laurence Stallings (book). It starred John Boles, Joe E. Brown and Vivienne Segal, and was the first all-color all-talking feature to be filmed entirely outdoors.
