Question:

"Defying Gravity" video (original broadway cast of Wicked)?

Does anyone know where I can see/download the full-length video (whole song from the "Elphie, why couldn't you stay calm for once instead of flying off the handle!" to the end of the song/Act 1) of "Defying Gravity" from Wicked the musical with Idina Menzel and Kristin Chenowith on it?

Best Answer - Chosen by Asker: You should try www.youtube.com. I know they have the full length "Popular," but I'm not sure about Defying Gravity.
