The Roy Rogers Show was a western radio program that focused on the adventures of Roy Rogers, one of the most popular singing-cowboy movie stars of the time. The show seamlessly blended western music, campfire banter, and thrilling adventures in which justice triumphs over evil. Roy Rogers provided much of the show's vocal music, with his band "The Sons of the Pioneers" featuring heavily in the series, as well as his steed Trigger, his wife Dale Evans, and a rotating cast of comical sidekicks. The show's opening theme "It's Round-Up Time on the Double-R-Bar" was later replaced by the famous "Happy Trails" song written by Dale Evans, and Roy would often close the show with the phrase, "Goodbye, good luck, and may the good Lord take a likin' to ya."
The Roy Rogers Show first aired in 1944 on the Mutual Network and continued to be broadcast on both Mutual and NBC over a decade until its conclusion in 1955. The show had multiple sponsors throughout its tenure, including Goodyear Tire and Rubber Company, Miles Laboratories, Quaker Oats, Post Toasties, and Dodge automobiles. The series was one of the first radio programs to be transcribed due to Roy Rogers' busy schedule with personal appearances and film-making. There were also several TV adaptations of the show produced during its run.
