Three young, extraordinarily gifted musicians and siblings, Biko’s Manna, traveled from South Africa to perform a rendition of “Don’t Worry Be Happy” for the four judges in a video that was uploaded to YouTube.

They also possess an abundance of talent! Simon Cowell is immediately won over by their performance in the first few seconds. Howie Mandel even said he thought they had what it took to win the tournament as a whole.

The lead vocalist has an amazing voice that is quite relaxing and pleasant—it’s definitely an angelic sound.

Their stage presence is also astounding for such a young artist. In front of hundreds of spectators and the four judges of the program, the kids all look completely at ease as they perform on stage.

They don’t appear in the least bit alarmed or uneasy. Everyone in the room gave the kids a standing ovation after they sang the Bobby McFerrin hit, and for good reason.

What a wonderful musical concert! With nothing but praise for them, the four judges expressed their admiration for one another.

These kids have probably gained an audience and following even if they do not end up winning the competition.
