 The film originally used Pink Floyd (qv)s "Shine On You Crazy  Diamond" repeatedly throughout the film, and this version was  screened at festivals. However, Pink Floyd charged a steep licensing  fee for use of its song outside of those festival screenings, and so  all instances of "Shine On You Crazy Diamond" were replaced, with  the song "Richochet Pt. 1" by Tangerine Dream (II) (qv), in order  for the film to be released in commercial cinemas.
