Rice was visiting singer Della Reese, who was considering buying a new Lincoln Continental for her drummer and band leader Calvin Shields for his birthday. Rice and other band members were teasing Shields about the pending gift, and Shields replied that he did not want a Lincoln; he wanted a Ford Mustang. Rice had never heard of the Mustang, which had just come out, but he teased Shields about wanting a smaller car. He decided there might be a song in the situation, changing it to be about a woman who doesn't want to do anything but ride around in her new car. Rice called the early version "Mustang Mama," but changed the title after Aretha Franklin suggested "Mustang Sally" because he used the name Sally in the chorus.
