"The Wiz Live!" is adapted from "The Wonderful Wizard of Oz" by L. Frank Baum, with a book by William F. Brown, and music and lyrics by Charlie Smalls. The production opened on Broadway in 1975 at the Majestic Theatre, starring Mills. It won seven Tonys, including best musical.

"The Wiz" tells the classic story hundreds of millions of people have read in the L. Frank Baum books and then saw in the much-beloved 1939 film "The Wizard of Oz," but retold in an African-American/multicultural context. Dorothy, a young woman from Kansas, is swept up in a tornado and relocated to a fantasy world that is inhabited by munchkins, good and bad witches, and, of course, flying monkeys. She eventually takes a path down a yellow brick road to find a wizard who can help her go home and along the way meets a scarecrow, tin man and cowardly lion, who all learn to help one another.
