Salon: "Iffy" on Darkland?

Drew Grant at Salon has an article titled, “10 pieces of culture we're feeling iffy about.” Number one on his list. . . Ghost Brothers!
.
Grant writes, “Stephen King and John Mellencamp are making a musical: It's called "Ghost Brothers of Darkland County" and it's based on the death of two brothers and a young girl. Suddenly, the lyrics of "Jack & Diane" seem way more ominous.” http://www.salon.com/entertainment/movies/feature/story/index.html?story=/ent/movies/feature/2011/04/02/pop_torn_greys_anatomy_judge_judy
If this is actually “news” to Grant, he’s been living under a rock with the Gico cavemen. Or, he doesn’t read Lilja’s library – shame on him if that is the case. But the bigger question is, what is there to feel iffy about a Stephen King musical? Well, in a word – Carrie. Okay, but this isn’t Carrie! I checked the synopsis.
.
The story is set in the imaginary town of Lake Belle Reve, Mississippi and focuses on the 1957 deaths of 2 brothers and a young girl and the legend that develops from them. Mellencamp had the idea for the story, pulling it from a story he heard years ago in his hometown of Seymour, IN. According to Mellencamp, the story is going to be more like King's "The Green Mile" and is an "American story about an American family." King and Mellencamp stated the play will have a very fascinating, unique style. Mellencamp also stated it will have a Tennessee Williams kind of feel to it and that he wants to cover all music Americans have made so far. Mellencamp has written around 20 songs; some of them are: "You Don't Know Me," "My Name is Joe," and "Tear This Cabin down." http://www.onlineseats.com/theatre/ghost-brothers-of-darkland-county-tickets/index.asp

(could we say “story” a few more times?)
.
It’s a “Green Mile” like musical that will have a “Tennessee Williams kind of feel to it.” Okay. NOW I'm feeling iffy!
.
Of course, some King books have succcessfully made it to stage. In particular, Misery. Adding music to a King work does sound iffy on the surface. But what should be noted is that this is not an adaptation of a King story with music being forced into it; this is a work created for the music.

Is horror good musical material? Ever see a production called The Phantom of the Opera? Oh, and get this, it wasn’t written as a musical! It started out as a rambling novel by Gaston Leroux.
