As well as the Morning Is Broken song, Eleanor Farjeon wrote several books of stories for children between the 1920s and 1950s, often including songs as part of the text. Her writing is truly delightful -- basically fairy-type tales without heavy moralising. The first book (I think) was called "Martin Pippin in the Apple Orchard". A later collection is "The Old Nurse's Stocking Basket" (or something similar). She also did a revised longer version of Cindarella that is much better than the original. I think a few of the books are still in print. A good library should have some of the books.
