PIGEON FORGE, Tenn. (AP) - So far holograms have been used in concerts to bring dead musicians back to life on stage. This time, it's to show Dolly Parton as a ghost. Parton's hologram will play the Ghost of Christmas Past in "A Christmas Carol" at her Dollywood resort in Pigeon Forge, Tennessee, starting on Saturday. The holograms of other actors will be used to portray the Ghost of Christmas Present, the Ghost of Christmas Future and Jacob Marley. Parton says she thought it was crazy when she was told she was going to be turned into a hologram, but when she saw it on stage, she couldn't believe it.
