There is a Chopin polonaise (or mazurka, I don't know) played in the scene where a minor Polish official (newly-promoted)drunkenly grabs a fire-extinguisher and prances onto the table d'hote and staggers down the length of the table while spraying the guests, bringing the festivities (and his new promotion) to an end. On the musical soundtrack, the Chopin piece isn't identified. Why is this?
And what was the Chopin piece that Wadja utilized for this scene?
