This young boy is amazing.

Astounding five (5) yr old!!!!   No music sheets needed. Seems to thoroughly enjoy playing these songs, and becomes fully absorbed in the flow of notes, as if he has heard/played these pieces 100's of times before!  He certainly hasn't had the years to comprehend what he's doing, nor practice to be this good, so somehow his brain and finger dexterity have been pre-programmed,when, how, why is a complete mystery! What a talent!
 
Mind boggling!
