デイ・トリッパー
Lennon told "Hit Parader" in 1972 that "Paperback Writer" was primarily written by McCartney: "I think I might have helped with some of the lyrics. Yes, I did. But it was mainly Paul's tune." Lennon also told "Playboy" in 1980: "'Paperback Writer' is son of 'Day Tripper', but it is Paul's song."
