All three versions came from the Web site of Canadian author Robert Munsch.
Hearing Robert Munsch read his own stories can be a revelation. He puts so much energy into the reading, in a way that kids seem to really enjoy. He also often deviates from the published text. Listening to him made me willing to take a lot more risks as a reader.
I read "Paper Bag Princess" to my daughter's kindergarten class, and then played them Munsch's rendition [0]. Whenever I go back, the kids ask if they can hear an author reading their own book.
