The major music theme in the movie is based on the work of P.I. Tchaikovsky "Barkarola" - a very beautiful piece, indeed. You can find many performances of it on youtube. The best among them, on my opinion is this:

Well, there's three different editions available: the widely available Polydor 841 584 edition with two tracks that are 20:00 suites but doesn't have all the music heard in the film; the Warner-Pioneer 29L2-93 with three tracks of suites running a total time duration of 45:20; and Odeon Soundtracks 852 035 with sixteen tracks running a total time duration of 45:17. Good luck! ; )
