This is the nth time that I've watched this, and it makes me cry....always!!! Especially in an interview he said, at times he is being bullied he would always run to his "friend". Asked who his friend was: HIS VOICE!!! When people recognized his voice, he said, "Now I know, I am significant. I am Paul Potts!"
Check this one too!
