If you haven't seen it, there's a viral video of a blind six-year-old from Ohio named Avett Ray Maness, singing "Bohemian Rhapsody" by Queen while he plays piano.
He was born blind in one eye, and has some vision in the other, and taught himself to play piano by ear . . . and he's really good.
He's performed for schools, and is doing a fundraiser in April.
