In the beginning, he plays "God Bless America" with his pre-programmed piano. The words to the tune are:
> God Bless America. Land that I love. Stand beside her, and guide her, Thru the night with a light from above.
The last 3 notes reveal how he's faking it. The most obvious is the last note -- it's a higher note (than the preceding one), but the ball hits a lower key.
(If you think of it as a magic act, it's still a good performance -- at least the timing is right.)
