Cashing on in at least the name of TV's popular BEVERLY HILLBILLIES, movies like this were often released exclusively in the Southern states. Generally there would be a rudimentary plot, a couple of guest stars who used to be bigger names than they were by that point and a whole bunch of country music stars performing in scenes that really don't have anything to do with the rest of the movie.
Jayne's career, as we noted the other day, had seen better vehicles. Mamie Van Doren, herself also a sex symbol holdover from the fifties, didn't have much of a film career beyond this but is still around and a fun presence on Facebook.
Country music was still a few years away from hitting the mainstream big.
