Elphabios: Your Guide to the Twenty Green Girls of WICKED Past!

A whole lot happened in Oz before Dorothy dropped in, and Wicked has been telling that story to Broadway audiences for 15 years at the Gershwin Theatre. The milestone won't go by uncelebrated, as in just days, NBC will throw a joyous Halloween party for the ages, featuring songs from the blockbuster musical hit and a cavalcade of special guest stars, including Tony Award winners Idina Menzel and Kristin Chenoweth. Additional guest performers include Ariana Grande, Adam Lambert, Ledisi, Pentatonix and the current Broadway company of "Wicked." "A Very Wicked Halloween" airs tonight, October 29th at 10PM ET/PT on NBC.

To get ready for tonight, we're giving you a crash course on the twenty ladies who have gone green on Broadway since 2003. Which ones did you see?
