Company members who appear at the event include Alison Luff (Elphaba), Jenn Gambatese (Glinda), Curt Hansen (Fiyero), Kim Zimmer (Madame Morrible) and John Davidson (Wizard) as well as members of the ensemble, band and touring staff.

A Wicked Night Before Christmas, according to press notes, "is part of an ongoing series of performances and appearances by the touring company to support charitable causes which advance Wicked's theme of acceptance and illuminate the musical's message that people should not be judged on first impressions. The company believes that in these divisive times we must come together to support those in need throughout the country and around the world. In its eight years on the road, the company has raised over $2.5 million in donations for Broadway Cares/Equity Fights AIDS and local AIDS service organizations all over the country."

In addition to the performance, there are live and silent auctions that include several opportunities to join the company backstage at the Oriental Theatre and a chance to bid on a walk-on role in a performance of Wicked.

Wicked is playing through Dec. 21 at the Oriental Theatre.

General admission to The Wicked Night Before Christmas is a $60 donation, which includes two drinks. A limited number of VIP tickets are available for a $100 donation and include priority seating as well as a 6:30 PM pre-show reception with members of the company.
