Roy Rogers saves Dale Evans from being hoodwinked by a rodeo competitor in this pleasant, and pleasantly tuneful, B-Western from Republic Pictures. Due to the mismanagement of old-timer Gabby Whittaker (George "Gabby" Hayes), The Brooks Rodeo is about to be gobbled up by competitor Frank Madden (Richard Powers aka Tom Keene), who also has designs on pretty owner Marjorie Brooks (Evans) herself. But when Gabby hires Roy Rogers and the Sons of the Pioneers as the new headliners, Madden and his henchman Ken Ferguson (Roy Barcroft) are forced to commit a bit of sabotage. With the aid of Trigger, "The Smartest Horse in the Movies," and radio announcer Marty Maizely (Lloyd Corrigan), Roy and Gabby manage to the goods on Ferguson and prevent Marjorie from marrying the sleazy Madden. Featuring early silent screen star Claire Du Brey as Dale Evans' faithful housekeeper, Lights of Old Santa Fe also presents such pleasant musical divertissements as Jack Elliott's title tune, Tim Spencer's "Trigger Hasn't Got a Pretty Figger", "I'm a Happy Guy in My Levi's Britches" and "Cowpoke Polka", and Ricardo Lopez Mendez' "Amor". The latter is performed by Dale Evans in both English and Spanish versions.
