A TEENAGER who started singing after being taken to a Donny Osmond concert by his mother has wowed the X Factor judges.

Dale Ali got a “yes” from all four judges on Sunday night – and proved particularly popular with Tulisa after changing the lyrics of his song to include her name.

The 17-year-old, from Catterick Garrison, North Yorkshire, is through to bootcamp after singing Olly Murs’ Thinking of Me. Dale even had the confidence to approach the judges’ table and sing directly to the former N-Dubz singer.

After his performance, Tulisa said: “I absolutely loved it, it’s a yes from me.”

Louis Walsh added: “Some people have a natural charm and you have a natural charm – you have four yeses.”

Dale, a former pupil of St Francis Xavier School, in Richmond , who is now studying musical theatre at York College while working parttime at a care home, said he began singing after his mother, Alison, took him to see Donny Osmond perform in Newcastle when he was ten.

“Ever since then I started listening to his CDs and practising,” he said.

Dale’s first public performance was at a school talent contest where he sang Cry Me a River and he has since performed a number of gigs in Darlington, Northallerton and the Catterick Garrison area.

However, the teenager said singing in front of the judges and the 5,000-strong crowd at the X Factor audition at the Newcastle Metro Radio Arena in June was his most nerveracking moment.

“Waiting backstage you can see the judges and I was so nervous, but it was fine as soon as I started singing,” he said Viewers will find out later this year if Dale makes it through the bootcamp to the live shows.

Even if he failed to win the contest, the teenager said he was glad he entered.

“It can open other doors – you just don’t know who is watching,” he added.

His TV performance has already attracted interest from the industry. Yesterday he received a call from a London management company hoping to work with him.
