sections", explaining that it was not publicly disclosed that Carl had suffered "a debilitating back injury" and had been "self-medicating and drinking". Sessions resumed in early March. Ultimately, a compromise was reached, with the album including a mix of covers and originals. Brian told an interviewer that "15 Big Ones started out as an album of nothing but oldies, but then we ran out of them. Halfway through, Mike Love decided to make the record half old and half new. I didn't like the idea at first, but he literally forced us to do it his way. I resented that." However, by the time they had finished in May, the group had recorded almost nothing but covers. Songs Originals "It's OK", written by Brian and Mike, is an upbeat song about celebrating summer fun. "Had to Phone Ya" was written by Wilson while his wife Marilyn was away in Europe. "Everyone's in Love with You", written about the Maharishi Mahesh Yogi, was Mike Love's second ever solo contribution to a Beach Boys album. "That Same Song" was described by Carlin as "a whimsical history of world music that came close to sparking the gospel fire it set out to ignite". "T M Song" begins with a mock argument between the band members, possibly based on the real life arguments that had been occurring among themselves. Two of the songs predated the album by several years. The first, "Susie Cincinnati", is Al Jardine's only writing contribution to the album. It was recorded in 1969 during the sessions for the album Sunflower (1970). Brian included it on 15 Big Ones "because it's a good song", although Dennis felt that it was a "silly piece of shit". "Back Home" was originally written in 1963 by Brian and his roommate Bob Norberg. It is semi-autobiographical; Brian sings in the chorus of wanting to return to Ohio, which happened to be the homestate of his great-grandparents. Carlin notes the 15 Big Ones version for featuring "a throbbing bass, bouncing organ riffs, and a spirited vocal from Brian." Cover versions According to Wilson, "We thought about songs that were standards and, since they were acceptable once, we figured they would be acceptable again. ... We figured it was a safe way to go." The eight selections included on the album were "Rock and Roll Music" (originally by Chuck Berry), "Chapel of Love" (originally by Darlene Love),
