John Lennon wrote a book after he joined The Beatles. He admitted that he could have been an author if he didn't pursue music.
In 1964, John Lennon extricated his public image from The Beatles when he published the book In His Own Write. The book, which was full of Lennon’s nonsensical poems and short stories, received acclaim from critics. It proved that even if he hadn’t been a famous musician, he may have been able to find success as a writer.
Lennon became a published author in 1964. It wasn’t necessarily something he sought out to do; he had simply amassed enough writing to fill a book.
“It’s about nothing. If you like it, you like it; if you don’t, you don’t. That’s all there is to it,” Lennon said of In His Own Write in The Beatles Anthology. “There’s nothing deep in it, it’s just meant to be funny. I put things down on sheets of paper and stuff them in my pocket. When I have enough, I have a book.”
He didn’t think he ever could have become a published author without The Beatles. Still, he knew he would have been a writer regardless of his level of fame. He wondered if he could have been a Beat poet.
“There was never any real thought of writing a book. It was something that snowballed,” he said. “If I hadn’t been a Beatle I wouldn’t have thought of having the stuff published; I would have been crawling around broke and just writing it and throwing it away. I might have been a Beat Poet.”
