The legend of 1900

[Luca_Capozzi]

Movie by Ennio Morricone, with Tim Roth.
In the last part of the movie, there are a piano duel between 1900 and a jazz piano player... 1900 performs a great classical piece that, to me, resembles something of Rachmaninov... any one know the name of this song?

thx

I saw the movie (and read the book) and it´s really great! Don´t know what that particular piece of music could be though... Perhaps it´s just something scored for the film even!?
