Presented from 8 AM to 6 PM on Sirius channel 108 and XM channel 139, the special will feature Emmy-winning "South Park" writers Matt Stone and Trey Parker, as well as Tony Award-winning Avenue Q songwriter Robert Lopez, and Tony-nominated Book of Mormon co-director and choreographer Casey Nicholaw.

Also featured on the interview is Book of Mormon producer Anne Garefino, also the executive producer for "South Park," and cast members Josh Gad, Andrew Rannells, Nikki M. James, Rory O'Malley and Michael Potts. The radio special will be rebroadcast April 3 from 8 AM to 3 PM.

Parker co-directs The Book of Mormon with Nicholaw (The Drowsy Chaperone, Spamalot), who also choreographs. Book, music and lyrics are by Parker, Stone and Lopez. The Book of Mormon began previews Feb. 24 and officially opened March 24 at the Eugene O'Neill Theatre.

Gad ("The Daily Show with Jon Stewart") and Rannells (Jersey Boys) star as an unlikely pair of Mormon missionaries who venture from Salt Lake City to AIDS-ravaged Uganda in the hopes of converting villagers with the story of Joseph Smith and the founding of the Mormon Church. The problem is: Only one of them has actually read the book.

For tickets, $59-$137, phone (212) 239-6200 or visit Telecharge. The Eugene O'Neill Theatre is located at 230 West 49th Street. Here's Playbill.com's interview with the Book of Mormon authors:
