IT was a Neopolitan love song sung in a tent near a Morrison’s supermarket in Liverpool that made the big difference to the lives of Welsh singing brothers Richard and Adam Johnson.

The tent had been set up for last-minute auditions for Britain’s Got Talent . The boys, who happened to be passing, asked if they could have a go, went in and sang a couple of lines from O Sole Mio (Just One Cornetto) which the late Luciano Pavarotti used to sing.

Those few unexpected minutes got Richard and Adam into the auditions at Birmingham. They got through to the final, where their version of The Impossible Dream was interrupted when a violinist in the orchestra accompanying them stood up and hurled an egg at competition judge Simon Cowell.

The incident didn’t scramble their chances, however. They came third. Now, with three albums released, record sales of 500,000 and a second UK tour pending, Richard and Adam are ready for anything – with a little help from their nan, Lorna Flack.

Adam said: “We used to stay with her in Birmingham every holiday and she used to play classical music, this was around the time of the Three Tenors. We loved it. She was in the wings when we were doing Britain’s Got Talent.

“For us to be on the telly singing with her watching...she said she was on cloud nine. It was nice for us to give something back to her. She’ll be at most of the tour dates. She’s a little star. She loves it. She’s just funny.”

Appropriately, the forthcoming tour opens in Liverpool, where Richard and Adam did that last-minute Britain’s Got Talent audition less than two years ago. They’ll be promoting their third album, At the Movies.

Joining them on the tour will be Sophie Evans, the Welsh girl who made her debut as Dorothy in Andrew Lloyd Webber’s new production of The Wizard of Oz at the London Palladium. She also appeared in the movie Pride with Bill Nighy and Imelda Staunton.

When they reach St George’s Hall on February 28, Richard and Adam are hoping to be joined by local singing talent. They want between 20 to 30 singers to take part in a performance of Can You Feel the Love Tonight? from The Lion King. The choir will also be able to sing one number of their own.

“We first did this at a Christmas show in Port Talbot. It gave so much more power to a song. People were saying it was a great touch.

“We had a meeting with out management in London last February and we said it would be good to get a choir. We’re looking forward to it,” Adam added.

Choirs should post a video of themselves performing either to Richard and Adam’s Facebook page or send it by email to choirs@flyingmusic.com.
