Question: Who wrote the music for the muscial based on L. Frank Baum's book whose title is commonly shortened to The Land of Oz?

full_context: Document 1: Nathaniel D. Mann: Nathaniel D. Mann was an American composer best known for his work with L. Frank Baum. He composed at least two songs with Baum, "Different Ways of Making Love" and "It Happens Ev'ry Day," and another with John Slavin, "She Didn't Really Mind the Thing at All," for "The Wizard of Oz" stage musical in 1902, and in 1908, composed the first original film score (27 cues) for "The Fairylogue and Radio-Plays", one of the earliest feature-length fiction films (and the earliest film adaptations of the novels "The Wonderful Wizard of Oz", "The Marvelous Land of Oz", "Ozma of Oz", "John Dough and the Cherub", and "Dorothy and the Wizard in Oz", presented by Baum himself), which debuted September 24, 1908. With Baum, he also composed the musical "The King of Gee-Whiz" (dated February 23, 1905), which went through various titles such as "Montezuma" (November 1902), "King Jonah XIII" (September 1903), and "The Son of the Sun" (1905). This was collaboration with and based on a novel by Emerson Hough, which was never completed and the extant scenario published in 1969.
Document 2: Plays of L. Frank Baum: The plays of L. Frank Baum are an important aspect of Baum's writing career about which some of the least is known. While even most brief biographies, long before the Internet, have noted Baum's work as a playwright, these works have been rarely performed beyond his lifetime, and almost none have been published aside from two scenarios and a first act of three unfinished works in "The Musical Fantasies of L. Frank Baum", compiled with an introduction by Alla T. Ford. Aside from his youthful success with "The Maid of Arran", his blockbuster eight-year run with "The Wizard of Oz", his failure with "The Woggle-Bug", and "The Tik-Tok Man of Oz" as source material for his novel, "Tik-Tok of Oz", very little is known about his dramatic output, and mostly from the publications of Michael Patrick Hearn, Susan Ferrara, and Katharine M. Rogers. Hearn identifies 41 different titles in the bibliography of the 2000 edition of "The Annotated Wizard of Oz", plus one play without a title, although some of these titles clearly refer to drafts of the same play, such as the early titles of "The Tik-Tok Man of Oz".
Document 3: The Woggle-Bug (musical): The Woggle-Bug is a musical based on "The Marvelous Land of Oz" by L. Frank Baum, with book and lyrics by the author and music by Frederic Chapin that opened June 18, 1905 at the Garrick Theater in Chicago under the direction of Frank Smithson, a Shubert Organization employee. The musical was a major critical and commercial failure, running less than a month. Chapin, however, had proven quite saleable to the publisher, M. Witmark and Sons, and many of the songs were published. The music director was Frank Pallma. The surviving sheet music was published by Hungry Tiger Press in 2002.
Document 4: The Emerald City of Oz: The Emerald City of Oz is the sixth of L. Frank Baum's fourteen Land of Oz books. It was also adapted into a Canadian animated film in 1987. Originally published on July 20, 1910, it is the story of Dorothy Gale and her Uncle Henry and Aunt Em coming to live in Oz permanently. While they are toured through the Quadling Country, the Nome King is assembling allies for an invasion of Oz. This is the first time in the Oz series that Baum made use of double plots for one of the books.
Document 5: List of Oz books: The Oz books form a book series that begins with "The Wonderful Wizard of Oz" (1900) and relate the fictional history of the Land of Oz. Oz was created by author L. Frank Baum, who went on to write fourteen full-length Oz books. All of the Baum written books are in the public domain in the United States. Even while he was alive, Baum was styled as "the Royal Historian of Oz" to emphasize the concept that Oz is an actual place. The illusion created was that characters such as Dorothy and Princess Ozma related their adventures in Oz to Baum themselves, by means of wireless telegraph.
Document 6: Dorothy and the Wizard in Oz: Dorothy and the Wizard in Oz is the fourth book set in the Land of Oz written by L. Frank Baum and illustrated by John R. Neill. It was published on June 18, 1908 and reunites Dorothy with the humbug Wizard from "The Wonderful Wizard of Oz" (1900). This is one of only two of the original fourteen Oz books (the other being "The Emerald City of Oz" (1910), to be illustrated with watercolor paintings.
Document 7: Babes in Toyland (operetta): Babes in Toyland is an operetta composed by Victor Herbert with a libretto by Glen MacDonough (1870–1924), which wove together various characters from Mother Goose nursery rhymes into a Christmas-themed musical extravaganza. Following the extraordinary success of their stage musical "The Wizard of Oz", which was produced in New York beginning in January 1903, producer Fred R. Hamlin and director Julian P. Mitchell hoped to create more family musicals. MacDonough had helped Mitchell with revisions to the "Oz" libretto by L. Frank Baum. Mitchell and MacDonough persuaded Victor Herbert to join the production. "Babes in Toyland" features some of Herbert's most famous songs – among them "Toyland", "March of the Toys", "Go To Sleep, Slumber Deep", and "I Can't Do the Sum". The theme song "Toyland", and the most famous instrumental piece from the operetta, "March of the Toys", occasionally show up on Christmas compilations.
Document 8: The Magical Mimics in Oz: The Magical Mimics in Oz (1946) is the thirty-seventh in the series of Oz books created by L. Frank Baum and his successors, and the first written by Jack Snow. It was illustrated by Frank G. Kramer. The book entered the Public Domain in the United States, when its copyright was not renewed as required.
Document 9: Glinda of Oz: Glinda of Oz is the fourteenth Land of Oz book written by children's author L. Frank Baum, published on July 10, 1920. It is the last book of the original Oz series, which was later continued by other authors. Like most of the Oz books, the plot features a journey through some of the remoter regions of Oz; though in this case the pattern is doubled: Dorothy and Ozma travel to stop a war between the Flatheads and Skeezers; then Glinda and a cohort of Dorothy's friends set out to rescue them. The book was dedicated to Baum's second son, Robert Stanton Baum.
Document 10: Wicked (musical): Wicked: The Untold Story of the Witches of Oz is a Broadway musical with music and lyrics by Stephen Schwartz and book by Winnie Holzman. It is based on the 1995 Gregory Maguire novel "", an alternative telling of the 1939 film "The Wizard of Oz" and L. Frank Baum's classic 1900 story, "The Wonderful Wizard of Oz". The musical is told from the perspective of the witches of the Land of Oz; its plot begins before and continues after Dorothy's arrival in Oz from Kansas, and it includes several references to the 1939 film and Baum's novel. "Wicked" tells the story of two unlikely friends, Elphaba (the Wicked Witch of the West) and Galinda (whose name later changes to Glinda the Good Witch), who struggle through opposing personalities and viewpoints, rivalry over the same love-interest, reactions to the Wizard's corrupt government and, ultimately, Elphaba's public fall from grace.
Document 11: The Marvelous Land of Oz: The Marvelous Land of Oz: Being an Account of the Further Adventures of the Scarecrow and the Tin Woodman, commonly shortened to The Land of Oz, published on July 5, 1904 , is the second of L. Frank Baum's books set in the Land of Oz, and the sequel to "The Wonderful Wizard of Oz" (1900). This and the next 34 Oz books of the famous 40 were illustrated by John R. Neill. The book was made into an episode of "The Shirley Temple Show" in 1960, and into a Canada/Japan co-produced animated series of the same name in 1986. It was also adapted in comic book form by Marvel Comics, with the first issue being released in November 2009. Plot elements from "The Marvelous Land of Oz" are included in the 1985 Disney feature film "Return to Oz".
Document 12: Journey Back to Oz: Journey Back To Oz is a 1972 American animated fantasy-adventure film and an official sequel to the 1939 Metro-Goldwyn-Mayer film "The Wizard of Oz" produced by Filmation. It is loosely based on L. Frank Baum's second Oz novel, "The Marvelous Land of Oz", although Baum received no screen credit. However, the Wizard was nowhere to be found, at least in the theatrical version of the film. A television version shown in 1976 on ABC featured live-action segments starring Bill Cosby as the Wizard.
Document 13: The Magic of Oz: The Magic of Oz: A Faithful Record of the Remarkable Adventures of Dorothy and Trot and the Wizard of Oz, Together with the Cowardly Lion, the Hungry Tiger and Cap'n Bill, in Their Successful Search for a Magical and Beautiful Birthday Present for Princess Ozma of Oz is the thirteenth Land of Oz book written by L. Frank Baum. Published on June 7, 1919, one month after the author's death, "The Magic of Oz" relates the unsuccessful attempt of the Munchkin boy Kiki Aru and former Nome King Ruggedo to conquer Oz.
Document 14: The Wizard of Oz (2011 musical): The Wizard of Oz is a musical based on the 1939 film "The Wizard of Oz", with a book adapted by Andrew Lloyd Webber and Jeremy Sams. The musical uses the Harold Arlen and E. Y. Harburg songs from the film and includes some new songs and additional music by Andrew Lloyd Webber and additional lyrics by Tim Rice.
Document 15: L. Frank Baum's Juvenile Speaker: L. Frank Baum's Juvenile Speaker: Readings and Recitations in Prose and Verse, Humorous and Otherwise is an anthology of literary works by L. Frank Baum, author of the Oz books. The book was first published in 1910, with illustrations by veteran Baum artists John R. Neill and Maginel Wright Enright; a subsequent 1912 edition was retitled Baum's Own Book for Children. The book constitutes a complex element in the Baum bibliography.
