Hi Ken,
Yes, I did recognise the piece. One I do like, and it certainly sounded good with those orchestral voices. Wonder what Chopin would have thought if it? Quote from Wikipedia:
Frédéric François Chopin was a Polish composer and virtuoso pianist of the Romantic era who wrote primarily for solo piano. He has maintained worldwide renown as a leading musician of his era, one whose "poetic genius was based on a professional technique that was without equal in his generation".

PS. I didn't know Chopin was Polish!
