Chi Mai is very well known song by Ennio Morricone, especially thanks to movie Le Professionnel with J. P. Belmondo in leading role. I play on my Yamaha P140 digital piano.
Be sure to choose high quality link under video (if available) to hear much better stereo sound.
If you want only to listen, I recommend to download high-quality MP3 files from SkyDrive: http://jdem.cz/bxyk5
