In 2020, Willie and Bobbie Nelson co-authored a memoir called Me and Sister Bobbie: True Tales of the Family Band. In it, Willie wrote: "I've written a few books before, but there's one that passed me by. Probably passed me by 'cause the heroine is too humble to demand attention. The heroine is my sister, Bobbie. Bobbie's got the best story in our whole family. ... Without my sister, I'd never be where I am today. I've always needed her.".
