Ravi Adelekan’s version of A Million Dreams got the golden buzzer vote from Alesha Dixon to send him and his choir into the ITV show’s semi-finals.
The brave eight-year-old cannot sing alone as he lives with the effects of a tumour found aged six.
So he performed The Greatest Showman hit with a “Dream Team” of 50 patients, medical professionals, and sister Maya, five.
Ravi told The Sun today: “I didn’t see Alesha pressing her golden buzzer because we were bowing!
“There was all this confetti, but it took all of our brains a long time to draw the connection to the buzzer.

“I’ve met famous people before, but in the moment it felt different to that — like they believed in what we were trying to do.
“If we won it would help us reach our fundraising goal, but also winning would just bring so much more awareness of brain tumours.”
Ravi, who needed ten hours of surgery in 2021, has other big plans should he win including meeting his hero, ex-England striker and Match of the Day pundit Alan Shearer.
He was approached by BGT bosses who had seen his efforts to raise funds for Brains Trust and The Brain Tumour Charity.
A previous charity video of him singing the hit song featured cameos from Paloma Faith, Coldplay and Damon Albarn.
Mum Bethan, 42, from Brighton, said: “Ravi has always loved music but can’t use half his face, which affects his singing, plus he can’t hear out his left side.
“They say it takes a village to raise a child but it probably takes a city to support you through something as traumatic as this.
“We looked at all the incredible humans who’ve helped us and the choir is a microcosm of that.
“Ravi falls over a lot and can’t walk in a straight line but he just gets on with it.
“The best-case scenario is the tumour stays stable and doesn’t grow, and hopefully this is all he will have to deal with.”
Saturday’s BGT opener drew 5.8million viewers — ITV’s biggest audience of the year.
