In one of the most unforgettable moments of Britain’s Got Talent 2026, YouTube superstar, musician, and BGT judge KSI took the stage alongside internet legend Epic Sax Guy (Sergey Stepanov) for a high-energy performance that blended nostalgia, humor, and pure entertainment.
Known worldwide for his iconic saxophone riff from Eurovision 2010 that spawned countless memes, Epic Sax Guy returned to the BGT stage in the semi-finals. This time, he wasn’t alone. KSI — who has been a longtime fan — joined him for an epic duet that felt like meme history in the making.
From the moment the familiar sax melody hit, the audience erupted. KSI, fully embracing the moment in a show-stopping outfit, brought his signature energy, turning the performance into a lively, Eurovision-style party that had the judges and crowd laughing, cheering, and completely hooked.
In a heartfelt post-performance reflection, KSI shared how this was a dream realized. Over a decade ago, he made a YouTube video performing the Epic Sax song — never imagining he’d one day share the stage with the man himself on Britain’s biggest talent show. The judges praised the fun, chaotic brilliance of the act, with one even joking about injuring themselves from laughing so hard.
This unexpected collaboration perfectly captures the spirit of Britain’s Got Talent — where talent, personality, and unforgettable moments collide.
