My wife and I were watching this movie the other night and I thought how nice some of the music is for the movie. There was a segment featuring 'Peace Piece' which is one of my favorites but there was a piece I had a question on. What piano piece are Ray Liotta and Whoopie Goldberg playing together on the piano?

I did a search on the internet looking for clues and one person thought they were playing 'Peace Piece' which is of course wrong. I know 'Peace Piece'. Can anybody help me?
