The idea of the radio originates from the conversation between Grant and Jefferson concerning "Randy's Record Shop," a program that they both listened to as young boys growing up in the quarter. Thus, the radio not only provides a sense of kinship and connectedness between the two men; it also provides a link to their past, in which both enjoyed the same simple pleasures of youth. By reconnecting with that past, we can surmise that Grant realizes that the only thing that kept him from ending up like Jefferson was the role that fate and circumstance played in his life, enabling him to escape the narrow confines of his limited environment and exercise a freedom of choice that was not available to Jefferson. By realizing this, he is able, for the first time, to reach out to Jefferson as a friend, instead of regarding him as one of "those people" who got what they deserve.
Here again, Gaines fuses fiction with reality. He has said in an interview that "Randy's Record Shop" was a program that he himself used to listen to as a boy, growing up in the quarter. Renowned author and literary critic Henry Louis Gates, Jr., recalls in his autobiography Colored People: "If prime time [television] consisted of images of middle-class white people who looked nothing at all like us, late night was about the radio, listening to 'Randy's Record Shop' from Gallatin, Tennessee. . . . In 1956, black music hadn't yet broken down into its many subgenres, except for large divisions such as jazz, blues, gospel, rhythm and blues."
In Chapter 23, note that Jefferson prefers mental freedom (the radio) to physical freedom (the dayroom). Also, the references to the Bible ("Let there be light") reflect Jefferson's enlightenment.
We see a change in Sheriff Guidry's attitude toward Grant, as he accepts Grant's leadership role in Jefferson's care and directs Miss Emma and Rev. Ambrose to work with Grant in assuring that the radio does not become a source of disruption.
