In 1969, this Disneyland Records Storyteller album was released to commemorate the opening of Haunted Mansion. Intended as a simple promotional album, this recording has become a cherished childhood memory for many a Disneyland guest. "The Story and Song from The Haunted Mansion" includes original scenes and effects that never made it into the final attraction as it follows the story of two teenagers (voiced by Robie Lester and a young Ron Howard) who take refuge inside the eerie mansion during a rainstorm. (Synopsis from DisneyStore.com) The picture above shows Ron Howard in the Happy Days episode "Haunted", made about 5 years after the album.
