The 1967 animated Disney film "The Jungle Book" — inspired by Rudyard Kipling's book of the same name — springs to life in a new musical that had its world premiere at the Goodman Theater in Chicago. Written and directed by Mary Zimmerman, best known for her stage play based on Ovid's "Metamorphoses," the new show features all the songs from the movie, including the hit tune "The Bare Necessities."
