Cast members, dressed as Mormons, will perform the hit musical's opening number, "Hello!," as they proceed from dressing room to dressing room until they arrive at the dressing-room door of Tony host Neil Patrick Harris, according to the New York Post. The Mormon offering will segue into a medley from classic Broadway musicals.

"South Park" creators-writers Trey Parker and Matt Stone, and Tony-winning Avenue Q songwriter Robert Lopez collaborated on the script and score to Mormon, which earned Tony Awards for Best Book, Best Score and Best Musical.

The Book of Mormon also picked up Tony Awards for Best Direction (Parker and co-director/choreographer Casey Nicholaw), Best Performance by a Featured Actress (Nikki M. James), Best Orchestrations (Larry Hochman and Stephen Oremus), Best Scenic Design (Scott Pask), Best Sound Design (Brian Ronan) and Best Lighting Design (Brian MacDevitt).
