This guy is good. But the show definitely spun this the best they could. What they didn't mention is that he took private lessons in a school at Italy. While he was at the school he even won a contest and got to perform for Luciano Pavarotti.
The thing is, he paid for the school himself and was never paid to do a performance, thus he was still considered an amateur, not a professional.
He even has an album out now.
