The King of Rock and Roll is Little Richard's second album for Reprise Records, a follow-up album that contained one original Little Richard song, the gospel rock "In the Name" and a new song co-written by Producer H. B. Barnum, "Green Power", the single release; and versions of tracks by artists as diverse as Hank Williams, The Temptations, Martha and the Vandellas, Three Dog Night, and The Rolling Stones.
 The title track, a mock braggadocio that referenced Tom Jones, Elvis Presley, Ike & Tina Turner, Sly and the Family Stone, and Aretha Franklin, amongst others, upset some fans, although the album's title tune got good airplay in New York - a 1950s style jump blues, with an exceptional Little Richard shouting vocal!
 But fans and critics were further upset that the album did not feature acoustic piano and that most tracks were badly mixed, with an intrusive girl group chorus.
