Soundtrack
Despite several popular songs being present in the film, no soundtrack album was released. In 1999, bootleg copies of a "10th Anniversary Limited Edition" began to appear on Internet auction sites with the claim that Warner Brothers and RedDotNet had pressed 20,000 CD's for Six Flags Magic Mountain employees to give to customers entering the park. The discs were individually numbered out of "20,000" and were sold with most of the music featured in the film along with select cuts of dialogue. Forums on movie music sites such as SoundtrackCollector and Movie Music have declared the disc to be a bootleg put together by a fan. For instance, the cut, "Christmas Vacation Medley" (claiming to be the work of composer Angelo Badalamenti), is really a track called, "Christmas at Carnegie Hall" from Home Alone 2: Lost in New York by composer John Williams and does not actually contain any of Badalamenti's score from the film.
