As with most Cash shows, the genres covered ran the gamut from country music to rockabilly to even some folk rock. Similarly to the extended releases of both the San Quentin and At Folsom Prison that had been made available around the same time, Johnny Cash at Madison Square Garden includes numbers performed by Perkins, the Statlers and the Carters while Johnny was offstage. During this particular show, however, Cash introduced his father Ray and also Shel Silverstein, who wrote Cash's biggest pop hit, "A Boy Named Sue". Silverstein is the subject of some good-natured ribbing by Cash as he performs an uncensored version of "A Boy Named Sue". At the time of the recording, The Johnny Cash Show was in production and a popular TV series; its weekly "Come Along and Ride This Train" segment is referenced in the introduction to "As Long as the Grass Shall Grow."
