 P.L. Travers (qv) was a stickler about details in the script,  driving many of the Disney writers to distraction about Poppins  minutiae. After seeing the final film, she devised a list of changes  she wanted. Her requests went unheeded after Walt himself pointed  out that although she had SCRIPT approval, she didnt have FINAL  DRAFT approval. Among the things that she disliked was the Sherman  Bros. score. She wanted the only music in the movie to be period  pieces such as "Ta Ra Ra Boom De Ay" or "Greensleeves".
