Ringo Starr is joining the ranks of celebrities-turned-children's-authors. The Beatle plans to turn his 45-year-old song "Octopus's Garden" into a children's book, reports the Christian Science Monitor. Starr, though, will do so in collaboration with a pro—kids' book illustrator Ben Cort. It will be out next year via Simon & Schuster and will include a CD that has a previously unreleased music track from Starr, reports the Guardian. The musician also is releasing a book of photos called Photograph this month, which includes shots of the Beatles taken by Starr himself. CBS has a peek.
