When Biko’s Manna walked onto the America’s Got Talent stage, they looked like three sweet, slightly nervous kids with a guitar and a shaker. The trio of siblings from Johannesburg, South Africa smiled shyly as they explained they’d grown up making music together and had finally brought their family sound to one of the biggest stages in the world.
Their song choice was as bold as it was simple: Bobby McFerrin’s feel-good classic “Don’t Worry, Be Happy.” From the first notes, their harmonies locked in perfectly — warm, bright, and effortless. Big sister’s lead vocal soared while her brothers backed her up with guitar, rhythm and the kind of easy chemistry you only get from siblings who’ve been singing together for years. The whole performance felt like sunshine: relaxed groove, joyful smiles, and a natural stage presence that lit up the room.
The judges couldn’t hide their reactions. Howie Mandel called them “young and talented” and even hinted they could go all the way to the top prize, while Sofía Vergara loved how happy and united they were as a family. Heidi Klum said the long trip to America was “worth it,” and Simon Cowell praised their “beautifully simple” style and natural musical lane. By the final chorus the entire theatre was on its feet in a huge standing ovation — followed by four easy “Yes” votes that sent them straight through.
They arrived as a small sibling band from Joburg, hoping just to be heard. They left that stage as viral crowd-favorites whose joyful twist on a classic had the world smiling — exactly like their song promised.
