This video is currently going viral on the Internet. It shows a kid in a hat and Letterman jacket entertaining the crowd playing a variety of piano recitals including Csárdás. The video was originally uploaded on Dec 19, 2011.
There is another video labeled as Part 1 from the same uploader.
And here he is playing Csárdás.
I see a future appearance on The Ellen Show for Jake.
It certainly looks about right to me. What do you think?
