(Disneyland, 1969) An original vocal arrangement used by legendary voice actor Thurl Ravenscroft during recording of the Haunted Mansion's theme song, Grim Grinning Ghosts (The Screaming Song). Written by Buddy Baker and X. Atencio and arranged by Allan Davies, the photostatic musical arrangement is hand annotated in pencil, pen, and ink, throughout. Ravencroft's name has been added to the top and the piece is dated 2-14-69. There are changes to the time signature, musical notes added and subtracted, and the line "There's A Simple" is handwritten over a correction fluid redaction. This incredible document provides an important look behind the scenes of the creation of one of the most iconic songs in Disney history, which figuratively and literally sets the tone for one of the most popular theme park attractions in the world. Measuring 14"x11", the sheet music arrangement is in very good condition with yellowing, edge darkening, corner creasing, a faint vertical crease running the length of the page, and handling wear.
