Liberace is one of the two greatest piano players in my humble opinion. The other is Chico Marx.

As one of the greatest piano players, he plays that one song that everybody who has every played a song on the piano can do: chopsticks. It is amusing to see him do it. More amusing is all the variations he plays on it.

Here's a clip of him playing it in a medley in Las Vegas. I first saw this on MTV back in the late 80's.

Enjoy!
