The Wizard of Oz (1902 musical)
The Wizard of Oz was a 1902 musical extravaganza based on "The Wonderful Wizard of Oz" by L. Frank Baum, which was originally published in 1900. Much of the original music was by Paul Tietjens and has been mostly forgotten, although it was still well-remembered and in discussion at MGM in 1939 when the classic film version of the story was made. Although Baum is the credited bookwriter, Glen MacDonough was hired on as jokewriter after Baum had finished the script.
The Wicked Witch of Oz
Cosgrove Payes had published her first Oz book, "The Hidden Valley of Oz", in 1951 with Reilly & Lee, the publisher of the Oz series since the time of Baum. "The Wicked Witch of Oz" would have been the next book in the series, and was intended for publication in 1954 but Reilly & Lee cancelled the project, since the Oz books were no longer selling well. The book remained unpublished until the International Wizard of Oz Club brought out the first edition in 1993, with illustrations by Eric Shanower. The club declared it book 45 in the series. In the documentary, "", Payes states that she refused all requests to read her manuscript with "not 'til it's a book."
