Country music and country gospel loom large in the choice of songs. The songs of such country and Western legends as Bill Monroe, Ernest Tubb, Hank Snow and Gene Autry are among those featured. Lewis played most of the piano and Presley took nearly all of the lead vocals. The other participants easily follow Presley's lead with what seems a close familiarity with his choice of songs. Critics have remarked on the irony of this as rock & roll was branded as satanic music at the time.
