In 1950s "The Roy Rogers Show" made Bullet, the dog and Nellybelle, the jeep very popular household names. It also made the song, "Happy Trails to You" as the theme song for this western show very famous and greatly appreciated. It is the song that was always sung over the end credits of "The Roy Rogers Show".

In 1951, Foy Willing wrote a song titled "Happy Trails" for the movie starring Roy Rogers by Republic Pictures, "Spoilers of the Plains". Later, Dale Evans wrote her version of "Happy Trails". She used the first three notes of Foy's song and the same title. Dale did not give any public credit to Foy Willing in helping with her version.

Dale's is the version that went on to be popularly played and sung. Today, we find that numerous notable cover versions of Dale Evans' song has been produced by some well known artists (Janis Joplin, Van Halen, and Randy Travis).
