There are many talent scouting shows on television that offer a wide variety of performances. Some numbers leave studio audiences and viewers speechless.

This was the case for 10-year-old Calum Courtney from Essex, UK. Calum has autism, but despite that, he has trouble making friends and connecting with people. He is particularly good at communicating through music — in this way, he establishes contact with the public.

Once on Britain’s Got Talent, Calum gave the judges and audience a jaw-dropping number, the memories of which will last a lifetime.
