Closing Theme Song

Believe it or not, it's Van Halen. I think it's from their "Diver Down" album.

Bigvan is right, its Van Halen. I'm a huge fan of Roy Rogers and VH!

SOP may have been in the background but Roy and Dale sang it. Both were prolific recording artists, particularly gospel stuff.

O no,,Ill be humming that tune all day now,lol

Wikipedia to the rescue!
"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.
Van Halen is an American hard rock band formed in Pasadena, California, in 1972. Its 1978 debut album, Van Halen—featuring guitarist Eddie Van Halen, vocalist David Lee Roth, drummer Alex Van Halen, and bassist Michael Anthony—is widely considered to be among the most "original" and "revolutionary" albums to "change rock and roll."[1]
While Van Halen might have also sung the song, it was sung by Dale and Roy about 20 years before they formed the band.
