By the mid-1960s, John Lennon and Paul McCartney wrote their songs apart, but they turned to each other for help perfecting them. According to Lennon, he helped a great deal with some of McCartney’s most popular songs. He explained that while one song was McCartney’s “baby,” he helped write all but the first verse.
McCartney began working on “Eleanor Rigby” based on the image of someone picking up rice after a wedding. He believed this was so poignant that he wanted to write a song about loneliness.
When asked about the song, Lennon said it was “Paul’s baby, and I helped with the education of the child.” By this, he meant that the song would never have grown and matured if it hadn’t been for him.
“Ah, the first verse was his and the rest are basically mine,” Lennon said in the book All We Are Saying: The Last Major Interview With John Lennon and Yoko Ono. “But the way he did it … Well, he knew he had a song. But by that time he didn’t want to ask for my help, and we were sitting around with Mal Evans and Neil Aspinall, so he said to us, ‘Hey, you guys, finish up the lyrics.'”
