NBC embarks on its latest musical holiday tradition: a 3-hour LIVE event production of the groundbreaking Broadway show that brought Oz to life in a funky sing-along journey down the yellow brick road.

From Executive Producers Craig Zadan and Neil Meron comes an adventure of stunning spectacle and toe-tapping music.
