The little guy had an incredible performance on stage in the UK, delivering a song for millions of people. Learn what the judges had to say.

Calum Courtney, 10, was hesitant as he walked onto the stage on Britain’s Got Talent, but he was more than prepared to produce a stunning performance in front of everyone.

The guy suffers from a slight degree of autism. However, one cannot help but notice his controlled beat when playing the Jackson 5’s smash “Who’s Lovin’ You.”

When Calum entered the stage, judge Alesha Dixon questioned whether he was nervous, to which he answered that he wasn’t. The judges were taken aback as soon as he began.

Calum’s family members sobbed throughout his performance, moved by his vocal skills. Millions of people saw the video, which quickly went global.

When he was completed, judge David Williams proclaimed Calum “outstanding,” which brought tears to the boy’s eyes. His younger brother then went up onto the stage to embrace him.

Amanda Holden said it was “the greatest response we’ve ever received” and that his singing was “amazing.”
