NASHVILLE (AP) – John Mellencamp’s new musical with Stephen King was inspired by his own haunted cabin. The musical “Ghost Brothers of Darkland County” is about two sets of brothers, two of whom are dead. Mellencamp bought a cabin on Lake Monroe in Indiana and the owners told him it was haunted by two brothers who fought over a girl. Mellencamp didn’t care — until weird things started happening. He says things would move, he’d smell cigars and other funny smells and things would turn on and off. He sold the cabin. Mellencamp told the story to his agent, who also represents King, and the two decided to work together. The musical will tour this fall. A boxed set featuring Elvis Costello, Sheryl Crow, Kris Kristofferson and Rosanne Cash is available now.
