The John Mellencamp/Stephen King musical "Ghost Brothers of Darkland County," details of which were first revealed by Billboard in 2000, will finally open in April 2009 at Atlanta's Alliance Theatre.

Mellencamp wrote the score, while King wrote the script. Mellencamp previously said the play, which is set in Lake Belle Reve, Miss., in 1957, is about "two brothers; they're 19 years old or 20, maybe 18 or 21, who are very competitive and dislike each other immensely. The father takes them to the family vacation place, a cabin that the boys hadn't been to since they were kids."

"What has happened is that the father had two older brothers who hated each other and killed each other in that cabin," he continued. "There's a confederacy of ghosts who also live in this house. The older [dead] brothers are there, and they speak to the audience, and they sing to the audience.

"Ghost Brothers" will be directed by Peter Askin ("Hedwig and the Angry Inch"), who hopes to prep the production for an eventual Broadway run.

Mellencamp also told Billboard that King is "the sweetest guy you could ever meet; there's nothing weird about him or demonic or anything like that."

As previously reported, Mellencamp will be inducted March 10 into the Rock and Roll Hall of Fame in New York.
