Thanks to posts this week on Defamer and the New York Post's PopWrap, Web-izens have been buzzing about this juicy news: The creators of "South Park" are launching a satirical musical featuring Mormons and their magical underwear.

The supposedly bound-for-Broadway show by the controversial "South Park" writing team of Matt Stone and Trey Parker was said to star Cheyenne Jackson, an actor noted for his performance in such stage plays as "Damn Yankees" and "Xanadu" and the premiere run of "Altar Boyz." An item in a New York Post blog said rehearsals were set to begin in December for a 2009 release of a comedy based on members of The Church of Jesus Christ of Latter-day Saints, and quoted Jackson describing the show as "hilarious, very acerbic and biting."

The only problem with news of the musical? A bit premature, admits Jackson's publicist Pete Sanders, who said his client made an off-hand comment about a satirical musical with Mormon characters with a reporter. "It was something that slipped out and it's actually not taking place now," Sanders said. "It's something that is in the future. It was one of those things that blew up. It's not even valid at this point. "

Composer and writer Robert Lopez, best known for his off-beat puppet musical, the Tony Award-winning "Avenue Q," said he's working on the project with the South Park team. But the project is still in the early development stage, he said, and it would be premature to say much about the musical.

Officials at "South Park" headquarters, Comedy Central, wouldn't confirm the show's existence. "They are simply workshopping a project that the guys have been thinking about for a while, and it's nothing more than that," Jenni Runyan, the cable station's director of corporate communications.

The Defamer post earned some attention, but the story didn't breakout into a Web phenomenon, says writer Kyle Buchanan. "I do think people are interested in the idea, because the Mormon church has had a real spotlight put on it in the last month, and that makes the project unexpectedly topical," Buchanan said. "Certainly, the 'South Park' creators could hardly have wished for better timing."
