Ella Fitzgerald, in her first screen role, plays Ruby, who fills several roles as one of the employees of the ranch. At the opening rodeo, she is dressed as a rodeo clown, and comes to Anne's side when she is hurt. Later in the film, she can be seen removing an apron before singing. Ella sings A-Tisket, A-Tasket in the bus, as the ranch crew drives from the railway station to the ranch. Ruby and the other employees interact playfully during the song.
In the one dance scene in the film, a square dance is being held in a barn. The Merry Macs interrupt the square dance caller with the musical question, "What kind of old fashion jive is that you've got?" And end up telling him "Don't be a chump. Do a square dance, but make it jump." They then launch into an upbeat swing tune. The Macs sing "Ruby, Ruby. We want Ruby", and ask her to come out and sing jive. She takes off her apron and sings a few verses. Still singing, she introduces dancers who will "show you how they drop the square. You know. Back in Harlem up on Sugar Hill." Several couples come out and put on quite a display of Lindy Hop. Ruby and the Macs each take a turn with additional verses, and over a dozen couples take the floor doing swing. Well known swing dancers Dean Collins and Jewel McGowan dance along side the other couples in this scene. Although Dean is known for a smooth style of Lindy, he and Jewel perform two "around the block" moves, as well as some energetic kicks during their short time on camera. Most of the songs in the film are cowboy songs, which were very popular at the time. The presence of Ella Fizgerald and swing dancers demonstrates another popular music and dance of the early 1940s.
