taped for use at the Ivor Novello Awards night in March 1967, McCartney and Lennon said that the song's melody was created by combining two different songs they had been working on separately. Lennon recalled that McCartney brought in the chorus ("the submarine... the chorus bit"), which Lennon suggested combining with a melody for the verses that he had already written. McCartney commented in 1966: "It's a happy place, that's all ... We were trying to write a children's song. That was the basic idea." Their working manuscript for the lyrics shows a verse crossed out and an accompanying note from Lennon reading: "Disgusting!! See me." Scottish singer Donovan contributed the line "Sky of blue and sea of green". In 1972, Lennon made the following statement about the song's authorship: "Both of us. Paul wrote the catchy chorus. I helped with the blunderbuss bit." In 1980, Lennon talked further about the song: Yellow Submarine' is Paul's baby. Donovan helped with the lyrics. I helped with the lyrics too. We virtually made the track come alive in the studio, but based on Paul's inspiration. Paul's idea. Paul's title ... written for Ringo." In his 1997 authorised biography, Many Years from Now, McCartney recalled coming up with the initial idea while lying in bed, adding that "It was pretty much my song as I recall ... I think John helped out... but the chorus, melody and verses are mine."

He says this solo recording debunks the widely accepted view that "Yellow Submarine" was merely a McCartney children's song dashed out for Starr, and that it conveys a deeper emotional resonance than was previously apparent. Concept and composition Author Steve Turner writes that in its focus on childhood themes, "Yellow Submarine" fitted with the contemporaneous psychedelic aesthetic, and that this outlook was reflected in George Harrison's comments to Maureen Cleave in his "How a Beatle Lives" interview, when he spoke of an individual's purity at birth and gradual corruption by society. Cleave likened his perspective to a contention put forward in William Wordsworth's poetry. In Many Years from Now, McCartney says he "started making a story, sort of an ancient mariner, telling the young kids where he'd lived" and that the story line became gradually
