Willie Nelson and his sister and Family band member Bobbie Nelson have announced a new memoir, Me And Sister Bobbie: True Tales of the Family Band. The book is due out Sept. 15.

“After being abandoned by their parents as very young children and becoming each other’s abiding relationship for more than eight decades, this dual memoir, told in alternating chapters, weaves together Willie and Bobbie’s journeys as they experienced them both side-by-side and apart, with powerful, emotional never-before-told recollections from their personal lives and careers,” reads a press release.

In addition, the Nelsons are also set to release a children’s picture book (tentatively titled Sister, Brother, Family: Our Childhood in Music), which is due out in September of 2021.
