A North Wales male choir is set to appear on Britain's Got Talent tonight.

Johns' Boys Male Chorus, based in Rhosllanerchrugog - near Wrexham, will sing in front of Britain's Got Talent (BGT) judges Simon Cowell, Amanda Holden, Alesha Dixon and Bruno Tonioli on Saturday's (April 29) show, in the hope of making it through to the next round of the ITV show. 

The award-winning choir consists of male singers ranging in age from 14 to 73. 

A teaser clip of the choir's performance on the show has been released by BGT with the description: "Welsh Choir Johns' Boys move us with ANGELIC vocals".

The clip shows the judges, crowd and presenters Ant and Dec lost for words by the performance.

People have already begun wishing Johns' Boys Male Chorus good luck ahead of tonight's show. 

Oswestry School, on Facebook this morning, said: "Get your alarms set for 8 pm this evening and tune into ITV to see Johns' Boys Male Chorus, Welsh Male Choir, formed and directed by our wonderful Director of Music, Aled Phillips take to the stage on Britain's Got Talent.

"As if that isn’t exciting enough, you may spot two very familiar faces, the two youngest members of the group are our very own Oswestry School pupils, Dan and Akaash.

"Wishing them all the best of luck. We can’t wait!"
