"Talk to Me" (originally by Little Willie John), "Palisades Park" (originally by Freddy Cannon), "A Casual Look" (originally by the Six Teens), "Blueberry Hill" (originally by Fats Domino), "In the Still of the Night" (originally by the Five Satins), and "Just Once in My Life" (originally by the Righteous Brothers). "Rock and Roll Music" was chosen, according to Love, because he felt that the band could possibly repeat the success they had with covering Berry's "Sweet Little Sixteen" as "Surfin' U.S.A." (1963). Dennis was originally slated to sing the lead on "Blueberry Hill", but Wilson gave the part to Love so that Love would not feel left out. "Palisades Park" was the source of inspiration for the Beach Boys' songs "County Fair" (1962) and "Amusement Parks U.S.A." (1965). Carl recorded his vocal in one take. Brian praised Carl's performance and ranked it as "one of my top five Beach Boys vocals. He nailed it." In the assessment of musicologist Philip Lambert, most of the covers remained faithful to the originals, however, "Blueberry Hill", "Talk to Me", and "Palisades Park" were the exceptions in which the listener gets "more of a sense of the younger Brian Wilson, not just reproducing originals but dignifying them with his own personal flavorings". Outtakes Although they were not included on the album, the band also recorded versions of "Sea Cruise", "On Broadway", "Mony, Mony", "Running Bear", "Shake, Rattle and Roll", "Secret Love", "Don't Fight the Sea", "Peggy Sue", "Michael Rowed the Boat Ashore", and "Let's Dance". Other discarded tracks included the originals "Short Skirts" (Brian), "Gold Rush" (Jardine), "Lisa", "Glow, Crescent, Glow" (Mike), "10,000 Years Ago", and "Rainbows" (Dennis). Packaging and artwork Group Therapy, a title proposed by Dennis, was rejected in favor of Dean Torrence's suggestion, 15 Big Ones, which referred to both the number of tracks and the group's 15th anniversary. It was packaged with cover artwork that showed photos of the individual band members inside five interlocking rings, resembling the logo for the Olympic Games. This was an intentional reference to the fact that 1976 had been an Olympic year. Mike Love reflected, "The images of Brian, Dennis, Carl, Al, and me in five interlocking circles could have been a metaphor for five bandmates united in common purpose, or five guys living in their separate worlds. With us, it was both." A logo that displayed the band's name, designed by Torrence, was
