The young boy gave a great performance when he sang on stage in the UK in front of millions of people. Learn what the judges have to say.

Calum Courtney, age 10, may have looked nervous when he took the stage on Britain’s Got Talent, but he was more than ready to give a powerful performance in front of everyone.

A mild form of autism affects the boy. But you can’t help but notice how well he kept the beat when he sang “Who’s Lovin’ You” by the Jackson 5.

When the kid got up on stage, judge Alesha Dixon asked him if he was nervous. Calum said he wasn’t, and the judge agreed. The judges were shocked as soon as he started.

Calum’s family members were so moved by his singing that they cried during his performance. The video was also watched by millions of people, and it quickly went viral.

When Calum was done, the judge, David Williams, said he was “brilliant,” which made the boy cry with happiness. After that, his younger brother ran out onto the stage to give him a hug.

Amanda Holden told him, “It was the biggest response we’ve ever gotten,” and she said that his singing was “fantastic.”
