I too was surprised when I clicked the audio link to find it playing the whole tracks. The quality is wanting though but good enough for anyone exploring the score.
I don't think Rozsa liked to talk about this score judging the response he gave (virtually none) on the Pav DVDr. Yet the music is such a great listen away from the film. I have to confess that I have never seen the whole movie, only the last 20 minutes.
