Spoilers of the Plains is a 1951 American Western film directed by William Witney, and starring Roy Rogers and Penny Edwards, with Foy Willing and the Riders of the Purple Sage.

[9][10] In 1951, Willing had written a song titled "Happy Trails" for the movie.

Subsequently, the first three notes of his song and its title were used by Dale Evans in writing her version of "Happy Trails" for both the original The Roy Rogers Show and the short-lived The Roy Rogers and Dale Evans Show, which aired on ABC in 1962.

Dale's is the version that is popularly played and sung today, albeit without giving credit to Willing.
