Background: Allen was born in San Francisco, California, to George Allen and Margaret Theresa ("Molly") Allen (nee Darragh; later Mrs. Edward Pidgeon), who were both of Irish Catholic extraction. She made her first appearance on stage at age three and was given her first role on the radio by Eddie Cantor. She was educated at the Star of the Sea Convent School and during that time became a talented dancer.
Context: In the early 1930s, Burns and Allen made several short films, preserving several of their classic vaudeville routines on celluloid. They also made two films with W. C. Fields--International House (1933) and Six of a Kind (1934). In 1937, Burns and Allen starred with Fred Astaire in A Damsel in Distress, a musical with an original score by George Gershwin, which introduced the song "A Foggy Day". It was Astaire's first RKO film without dancing partner Ginger Rogers.  Astaire's co-star Joan Fontaine was not a dancer, and he was reluctant to dance on screen alone. He also felt the script needed more comic relief to enhance the overall appeal of the film. Burns and Allen had each worked in vaudeville as dancers ("hoofers") before forming their act, and when word of the project reached them, they called Astaire and he asked them to audition.  Burns contacted an act he had once seen that performed a dance using brooms. For the next several weeks, he and Allen worked at home to learn the complicated routine for their audition. When they presented the "Whisk Broom Dance" to Astaire, he was so taken by it, that he had them teach it to him and it was added to the film. Their talents were further highlighted as they matched Astaire step by step in the demanding "Funhouse Dance". Throughout the picture, Burns and Allen amazed audiences and critics as they "effortlessly" kept pace with the most famous dancer in films, as many did not know either of them could dance.
