The medley consists of two Elvis Presley songs originally recorded in the 1950s. "That's All Right Mama" is a rockabilly song originally written and recorded by Arthur Crudup in 1946. Elvis Presley's version, released in 1954, became his first ever single. The song expresses a carefree attitude towards relationships, with the narrator saying that it's alright if his love interest does whatever she wants because he loves her no matter what. It reflects a sense of acceptance and freedom in love. "My Baby Left Me" is another Elvis Presley hit, released in 1956. The song is about heartbreak and the pain of a breakup. The narrator is left wondering why his baby left him without a word, questioning whether it was something he did or something he said that caused her to leave. He feels a deep sadness and longing for his lost love. Jennings' medley combines these two songs into one performance, giving a dynamic portrayal of contrasting emotions. The theme of love and relationships is central to both songs, with "That's All Right Mama" expressing a carefree acceptance of love, while "My Baby Left Me" portrays the pain and confusion of a breakup.
