Stephen Schwartz’s Wicked has played somewhere around 6,020 performances and counting, and last week the show cleared $2.7 million. The newly opened Frozen, despite some dreadful reviews, was at 99.9% capacity. And both musicals—Wicked since its 2003 opening, Frozen via the 2013 Disney animated smash that inspired it—are cultural phenomena, especially among musical-loving teenage girls who respond to the heroines’ frustrations, bonding with other young women (a sister, in Frozen’s case), and their eventual triumph over adversity. Both shows have earworm empowerment anthems that have saturated social media since their premieres, Wicked’s “Defying Gravity” and Frozen’s “Let It Go.” And both would seem ripe for spoofing, of the Forbidden Broadway sort. Who, except possibly their most die-hard fans, wouldn’t want to have a little fun at these monoliths’ expense?
