The opening song at the beginning of the movie is Pink Floyd's "Seamus" (Meddle, 1971). The version included in the movie is an instrumental version. The album version has vocals. During the theatre company's performance of pseudo-Hamlet, a sound bit from Pink Floyd's "Echoes" (also from Meddle, 1971) can be heard. The sound of the rapier sword is the first note heard in "Echoes".
