full_context: Document 1: Jennifer Gillis: Jennifer Kristine Gillis (born 26 April 1996) is a Canadian singer, dancer and actress with an extensive resume in musical theatre, television, singing, radio, recording, and animated voice-over work.

Document 2: 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 3: A Brand New Day (The Wiz song): "A Brand New Day", also known as "Everybody Rejoice", is a song from the 1975 Broadway musical "The Wiz" written by American R&B singer and songwriter Luther Vandross. (In 1976 Vandross recorded a version of the song for his album "Luther", on Cotillion Records.) In the play, the song is sung to celebrate because Dorothy has killed Evilene, the tyrannical Wicked Witch of the West. Dorothy, the Tin Man, the Cowardly Lion, and the Scarecrow sing the song with the newly freed Winkies, who were ruled and enslaved by Evilene. It was later featured in the 1978 film version, sung by cast members Diana Ross, Michael Jackson, Nipsey Russell, and Ted Ross (credited as The Wiz Stars). Given the all-Black cast of "The Wiz", the song's many references to freedom and new possibilities (especially as sung by African American characters who had just been freed from enslavement) certainly invoked the struggles and history of Blacks in America. In the onscreen version of the song, Nipsey Russell can even be heard exclaiming "Free at last!"—a reference to civil rights activist Martin Luther King Jr. (His impromptu addition to the song is not heard on the soundtrack album version, instead replaced by sung vocals by Diana Ross.)
