Wicked, the popular Broadway musical about an unlikely friendship between the witches of Oz and what a jerk the Wizard was, is running now at the Paramount. For this Thursday’s performance, Washington United for Marriage bought out the entire theater and is reselling the tickets to raise money for its Referendum 74/marriage-equality campaign. It should be a special show, with Governor Christine Gregoire in the house, an after-party with the cast, and the audience all amped up for the cause. (Paramount Theater, 911 Pine St, www.wickedformarriage.com, 7:30 pm, $74–$1,000)
