Derek Paravicini is 19. He's blind and he can't read or write. But he plays like a virtuoso.Life has been difficult for Derek from the start. He was born prematurely, weighing 0.7 kg. He battled on, but there was an excess of oxygen while he was sleeping in his incubator. It caused brain damage and blindness. Doctors feared the worst, but Derek lived and soon showed amazing musical abilities. At the age of three, he was playing a plastic organ. Then he started copying songs he heard, note for note.
