James Taylor is coming out with a new book this fall. And no, it won’t be a tell-all memoir. It’s a pop-up lullaby book, aptly titled “Sweet Baby James.’’ The 10-page hardcover is described as “a beautifully illustrated and stunningly produced pop-up book that brings to life James Taylor’s enduring 1970 classic song ‘Sweet Baby James’ for music lovers of all ages,’’ and it’s slated to be published in November by Blue Rider Press.
