Movie idea

I had an idea last night for a movie. A noted music critic encounters a busker on the street singing incomprehensibly while playing unusual instruments. He promotes him to the wider world. The singer does not appear to understand any language spoken to him. The chorus of speculation eventually reaches consensus that he somehow illegally entered the country, originating from some poorly known region of Central Asia, the Amazon, or some similarly obscure place. Linguists struggle to make sense of his language, and anthropologists are baffled by his novel instrumentation. Through it all, he wanders with apparent dim incomprehension, mute but for the enigmatic verses of his incomprehensible songs. Then we discover he's really an ordinary guy from Ohio who made his own instruments because he couldn't afford the real ones, sang made-up nonsense because he can never remember the words to any songs, and kept his mouth shut because he didn't want to get in trouble.
