Prepare to be happy! A children's book can grow and change, but the original is still there to enjoy, also. 1. Mary Poppins by P.L. Travers is a great children's book. 2. Disney made a classic kids' movie out of it with delightful songs by the Sherman brothers. 3. Cameron Mackintosh and Disney made a wonderful musical out of it, too. I saw it in New York this week. 4. A scene from it was recorded at Disney World which is exuberant and ridiculous and fun. Watch it on YouTube here (where you can see it larger) or see it below. 5. What a lot of joy and talent! It all started with a children's book.
