Melody of the Plains (1937)
by Hans J. Wollstein review

Billy Lenhart, a tiny, seven-year-old "bull-fiddler," made his screen debut in Melody of the Plains as Lafe McKee's youngest son -- which would just about make the ancient-looking, white-haired McKee the oldest pa of a preteen in movie history! Melody of the Plains, meanwhile, is about average for this kind of fare, a far cry from the Republic Pictures songfests starring Gene Autry or Roy Rogers, but pleasant enough in its own awkward way.
