The title is from the first line of the 1854 ballad "Jeanie with the Light Brown Hair" by Stephen Foster written about his wife, Jane.
Despite her character celebrating a birthday in her 20s, Patricia Barry was actually 40 when the show was broadcast.
Bob Hastings (Sam) and Mark Miller (Roger Hackett) both later appeared in I Dream of Jeannie (1965), another comedy featuring a genie that derived its title from the 1854 song "Jeanie with the Light Brown Hair" by Stephen Foster: Hastings played Homer Banks in The Used Car Salesman (1968) and Miller played Wild Bill Barrows in Ride 'Em Astronaut (1969).
Of the twelve credited actors for this episode, seven - Howard Morris, Mark Miller, Joyce Jameson, James Millhollin, Robert Ball, Jack Albertson, and Molly Dodd - made guest appearances on The Andy Griffith Show (1960).
