Combine the bluegrass of Appalachia with the Western Swing of Bob Wills; base the lyrics on stories of cowboys, cattle drives and the open vistas of the Wild West and you have Cowboy country. Put the primary performers (Roy Rogers and Gene Autry) on horses, cloth them in Western fringe get-ups and put them in the movies and you have a popular music in the 30’s and 40’s that retains a lasting legacy. The most famous song to come out of the movement is Gene Autrey’s “Rudolph the Red Nosed Reindeer”.
