Who knew that legendary outlaw William Bonney was a dead-ringer for Roy Rogers -- or vice versa -- yet here they both are and so is Pat Garrett, impersonated by Wade Boteler. Billy and Garrett have their final fatal encounter, but the former is barely cold before Roy and Trigger turn up in New Mexico looking for work. Everyone mistakes Roy for Billy, of course, but, as Marshal Conway (Joseph Crehan) explains, Billy couldn't sing if his life depended on it, so go prove you're not him. Or words to that effect. Roy naturally doesn't waste any time, but happily strums his guitar, and, accompanied by old pal "Frog" Millhouse (Smiley Burnette), warbles "Sing a Little Song About Anything" by Burnette and Eddie Cherkose. That almost settles the matter once and for all and Roy can go on with the pleasant business of romancing Lynne Roberts, who, to her surprise and bewilderment, found herself billed as Mary Hart in this her first of eight films with Rogers. According to Roy, someone higher up at Republic Pictures had suggested that "Rogers & Hart in Billy the Kid Returns" would look just great on a theater marquee. Although not much of an actor this early in his screen career, Roy Rogers is a pleasing personality, and with him at the helm, Billy the Kid Returns makes an easy 58 minutes or so of musical Western entertainment. But don't forget the sight of the usually so stalwart Roy, as Billy the Kid, coolly killing a man whose horse he has just stolen.
