"Happy Trails" by Dale Evans Rogers, was the theme song for the 1940s and 1950s radio program and the 1950s television show starring Roy Rogers and Dale Evans Rogers, always sung over the end credits of the program. Happy Trails was released in 1952 as a 78 RPM and 45 RPM by Rogers and Evans with the Whippoorwills and Orchestra on RCA Victor Records. It was re-issued in 1957 as a 45 RPM record on RCA Victor/Bluebird.
Roy Rogers earned the title King of the Cowboys for his enormous popularity in films, on television and radio, and in personal appearances. But before starring in his first film, Rogers earned his eventual place in the Country Music Hall of Fame by founding the Sons of the Pioneers.
The Pioneers’ unique harmony and their fine original songs—such as “Cool Water” and “Tumbling Tumbleweeds” led to a series of radio transcriptions, a Decca record contact, and film appearances in westerns, including two with Gene Autry.
