Isle of Wight musician, Jay Eatwell, has performed alongside pop star Mika and world renown classical musician, Lang Lang, at London's Royal Festival Hall, on the south bank of the River Thames.
The final of Channel 4's The Piano, as well as the full concert, are now available to watch on demand.
Mika opened the show with a pared-down version of his mega-hit, Grace Kelly, before Lang Lang demonstrated why he is considered to be one of the globe's best pianists.
25-year-old Jay, from Ventnor, was the first of the four amateur pianists to step onto the stage.

He won his spot after performing in the middle of busy St Pancras - little did he know Lang Lang and Mika were secretly watching, waiting to pick their favourites.
The Platform One alumni's train station performance, screened during episode one of the series, was a mash-up of classical and rap.
It led Lang Lang to declare Jay's work, 'a complete new artform', while Mika said he was: "Unique! The thing I wanted to hear. I'm going to adopt him!"
At the Royal Festival Hall, accompanied by a choir, Jay told the audience: "I'm not going to do much speaking, I am going to get straight to it.
"This is my song. It's called A Heart That's Cold."
Jay has been playing alongside his dad in pubs since he was little - on keyboard and mandolin.
He writes a song every day, but described filming with Channel 4 as nerve-wracking.
Three other performers were picked during episodes filmed at other stations around the UK.
Lucy, 13, from West Yorkshire was among them and hers was awarded performance of the night.
Lucy, who is blind, was escorted on stage by her music teacher, who she began working with aged just 3-years-old.
Following the performances, Mika and Lang Lang revealed they would also be giving each of the finalists a piano.
