RORY: I pledge myself to the Puffs, loyal I’ll always be …
FRANCIE: Sing out, Louise.
Francie is quoting from the 1962 musical comedy-drama film Gypsy, based on the 1959 stage musical, Gypsy: A Musical Fable, adapted from the 1957 autobiography Gypsy: A Memoir by burlesque entertainer Gypsy Rose Lee.
The film is about a domineering stage mother named Rose Hovick (Rosalind Russell), who drags her beautiful, gifted daughter June, and June’s shy, less-talented older sister Louise (Natalie Wood) around the country in her efforts to get them noticed. When June rebels and elopes, all of Rose’s efforts are poured into the seemingly impossible task of making Louise a star.
In the film (or the musical, originally starring Ethel Merman as Mama Rose), Rose makes her entrance by shouting, “Sing out, Louise!”, during her daughter’s audition. Francie is likewise encouraging the mumbling Rory to speak up while she recites her pledge.
In the film, the awkward Louise unexpectedly finds success as a burlesque star under the name Gypsy Rose Lee, which is what allows her freedom from her mother at last – a hint that shy Rory will find her own way to escape Francie’s clutches.
