Lady Gaga goes down hard but keeps on going.

This kid can really play the piano and sing. His classmates are falling in love with him as he plays Paparazzi by Lady Gaga. That blonde in the background is melting. His name is Greyson Michael Chance.

This is quite impressive and must have taken a while to master.
