Singer Wayne Newton makes his dramatic debut as Andy Walker, the son of domineering dirt farmer Willard Walker (Malcolm Atterbury). Desirous of pursuing a musical career, Andy is stopped in his tracks by his hidebound father. Ben Cartwright intervenes in this domestic dilemma-and along the way, guest-star Newton warbles such traditional tunes as "Old Joe Clark", "Scarlet Ribbons", "Danny Boy", and "The Old Rugged Cross". Also in the cast are Anne Jeffreys as Lily and Wayne Newton's real-life brother Jerry as Andy's brother Mike. First shown on April 10, 1966, "The Unwritten Commandment" was written by Jo Pagano, William Blinn and Dan Ullman. ~ Hal Erickson, Rovi
