The Pianist - Song

My first request, it's an important one. Not really. In the movie "The Pianist" many songs were played, most were written by Chopin. I'm trying to find the song that piano main character dude plays when the German officer confronts him, while he's hiding out in the attic or whatever it was. He sits down to prove that he's a pianist, and plays. Anyone have that MP3, the one from the movie? I've heard the song before, but that interpretation is the best.

shheessss....... only Chopin I know is a high end vodka....mmmmm.....vodka.....where r the bitches??

Never saw this movie, sorry :(
Some help here, pehaps ? (http://en.wikipedia.org/wiki/The_Pianist_(2002_film))

Music
* The piano piece heard at the beginning of the film is Chopin's Nocturne in C-sharp minor (Op. posth.)
* The piano music heard from somewhere within the abandoned house when Szpilman had just discovered a hiding place in the attic was the Moonlight Sonata by Beethoven. It would later be revealed that German officer Hosenfeld was the pianist. The German composition juxtaposed with the mainly Polish/Chopin selection of Szpilman.
* The piano piece played when Szpilman is confronted by Hosenfeld is Chopin's Ballade No. 1 in G minor, Opus 23. Also, the version played in the movie was shortened. The entire piece lasts approximately 9 minutes.
* The cello piece heard at the middle of the film, played by Dorota, is Bach's Cello Suite No. 1 Prelude
* The piano piece heard at the end of the film, played with an orchestra, is Chopin's Grande Polonaise brillante, Op. 22
* Shots of Szpilman's hands playing the piano in close-up were provided by classical pianist Janusz Olejniczak (1952-) of Poland.
