What Banjo on My Knee lacks in original story or compelling themes, it makes up for with warm, funny characters brought to life by delightful actors. Barbara Stanwyck shines as the uneducated "land girl", who marries Joel McCrea's "river boy" despite significant differences in their background and world view. Walter Brennan assays one of his best roles as McCrea's good-natured, contraption-playing father. ("When I'm low, it's music I need " he says, before launching into a song with his one-man band.) Buddy Ebsen, singing and dancing to the title tune, Walter Catlett, as a would-be lothario in hapless pursuit of Stanwyck, and Katherine DeMille, as a voluptuous harpy after McCrea, all turn in fine performances. One of the best elements in the film, however, is the music. We not only have Brennan 's rousing renditions of "Dixie" and "St. Louis Blues", but the latter tune rendered to perfection by the marvelous Hall Johnson Choir. The film doesn 't maintain the same level of charm found in its opening scenes throughout its length, but there is enough comedy and music to make Banjo on My Knee a film worth seeing.
