Two songs are performed live on stage for the first time during the show: "San Quentin" and "A Boy Named Sue". According to biographer Robert Hilburn, the decision had already been made for Cash to perform "San Quentin" twice as it was considered the major new song of the set, though on record Cash makes it appear as if the encore is due to audience demand; producer Bob Johnson ultimately chose to include both versions of the song on the album. According to Hilburn, Cash spontaneously decided to perform "A Boy Named Sue" during the show and neither the TV crew nor his band knew he planned to do it (though he gave them advance warning by announcing early in the show his intent to play it); he used a lyric sheet on stage while Perkins and the band improvised the backing.
