The dad-of-two, real name Jon Young, had the audience in peals of laughter tonight – getting a standing ovation from judges Amanda Holden, Alesha Dixon, Ashley Banjo (who is standing in for Simon Cowell) and David Walliams.

Jon even reduced the female judges to tears while performing a song he penned about his childhood, called ‘When I Was a Boy’.

Amanda said: “I think this is one of the best Golden Buzzers we’ve ever had on the show.

“After the year we’ve had, you’d be an amazing, brilliant winner.”

Walliams said it was “so personal” and “brilliant” while Dixon said the “magical” performance made her tearful and “ticks every single box”.

After learning of his success, the star quipped that “it wasn’t meant to get this far.”

And he joked to Ant and Dec: “Now I’ve got to write something else, a love song to my favourite television duo, Phil and Holly.

“It sounds so flippant to say I wasn’t expecting it but for so many reasons I wasn’t expecting it,” he added.

He grew up in Ipswich and Martlesham, attending the Holbrook boarding school from 1984 until 1991.

The comedy pianist was heavily involved in the New Wolsey youth theatre during his childhood.

“I’ve been playing the piano since I was a child,” he said.

“My dad brought me up playing it and I have been working as a musician playing the piano for 30 years now.”

The 47-year-old finally took the leap and auditioned for the hit show in February.
