I stumbled across A Mobile Phone Salesman called Paul Potts. A modest Paul tells the jury he shall sing opera, watch the jury’s faces. And then Paul starts to sing Nessun Dorma and really grabs the attention of both jury and audience. An amazing video!

You can also watch the video at YouTube, Paul sings Nessun Dorma.

Paul, although unknown in the competition, has a track record. According to Wikipedia Paul has spent two summers touring Northern Italy training with one of the major opera schools, training under top teachers Mario Melani and Svetlana Sidrova, and has taken part in master classes with Vilma Vernocchi, Katia Ricciarelli and Luciano Pavarotti. He has also performed with the Royal Philharmonic Orchestra.
