Callisto, the 28-year-old Sunderland-born singer who rose to fame with his theatrical Queen tributes, endured mixed treatment on BGT. During his semi-final, he had hoped to debut his original song Supernova, only to be overruled by producers and steered toward another Queen number. Dressed in a white boiler suit, Callisto delivered a passionate rendition of Somebody to Love — but Simon Cowell’s response was as measured as it was backhanded.
“I’m in two minds,” Cowell told him. “Do what you do best, which is, you are a really, really good Freddie Mercury tribute act — sorry, not impersonator, a tribute act. And for that, it was really, really good.”
Callisto, clearly rattled but refusing to shrink back, responded: “First thing I’d say is I sing with a passion, and I made a lot of people happy tonight, yeah? It doesn’t matter whether I sing my own. Yes, it was like a tribute to Freddy H. But the thing is, I sing my own songs, and I wanted to sing my own song. But anyway, it doesn’t matter.” He even teased the possibility of a final: “If I do get to the final, and it does have to be Queen, we all know there’s only one song that’s got to be… Radio Gaga.”

The exchange set social media alight. While some viewers criticized Callisto as “cocky,” many more rallied to his defense, praising his charisma and vocals. One fan wrote: “Simon will regret this. He failed to recognize real talent standing right in front of him.” Another echoed: “He hyped Olly to the skies but dismissed Mickey — that’s blatant favoritism.” Others simply declared Callisto “sensational” and “a Freddie tribute the world deserves.”

In contrast, 11-year-old guitar prodigy Olly Pearson was showered with instant acclaim from Cowell in the same season. Midway through his electrifying semi-final medley — complete with a rising platform and flaming guitar — Cowell smashed the golden buzzer before the other judges could even speak. “Why, because he was bloody brilliant, seriously. He’s so small, talented and charismatic. I went a little early, I’m sorry but I was so excited. You’re just so brilliant and talented. Really, really, really talented,” Cowell said.
The disparity has not gone unnoticed. As one fan commented: “If Simon really thinks Mickey is just a tribute act, then he doesn’t understand artistry at all.” Another added: “BGT keeps losing stars because Simon can’t see beyond his own bias.”

Meanwhile, the Paris flashmob — with Callisto arriving in a carriage to deliver vocals while Pearson’s guitar solos set the crowd ablaze — has become a cultural phenomenon, amassing more than 500 million views worldwide. Even Queen’s official account weighed in, declaring: “We absolutely love this.”
For Callisto and Pearson, the viral triumph has outshone their BGT experiences, proving that true talent doesn’t always need Cowell’s stamp of approval.
