Pizza delivery driver Jamie Pugh shock the judges with his singing skills on this week's Britain's Got Talent.
Pugh, 37, fears that his lack of sleep and major bout of nerves will ruin his chances at the Cardiff auditions.
Speaking before his performance, Pugh says: "I suffer from severe stage fright, it has totally crippled me, and I've come today to see if I can get through 3 minutes."
He adds: "In the day time I work three days a week driving a van and in the evenings I deliver pizza. I’m just a simple bloke from the Valleys, but my dream is to sing at the Royal Variety in front of a live orchestra."
However, the singer shows no signs of nerves during his emotional rendition of the West End hit 'Bring Him Home'.
"Donna, his proud partner is up on her feet in the audience looking emotional as Jamie starts his faultless performance," said a show source. "All three Judges look spellbound and at the end of the song the whole theatre is on its feet, bringing tears and a look of shock to Jamie's face."
Amanda Holden describes Pugh's vocals as "beautiful", while Piers Morgan claims that the singer is "incredible".
Rounding off the praise, Simon Cowell adds: "It's people like you the reason why we come to Wales every year, I think you could be a special talent, but you have to start believing in yourself."
Britain's Got Talent airs on Saturday at 8.20pm on ITV1.
