The 2012 series of Britain’s Got Talent kicked off on Saturday night, with the usual weird and wonderful auditions hoping to impress the new line-up of judges.

Viewers had their first chance to see newcomers Alesha Dixon and David Walliams in action – along with the return of Simon Cowell and Amanda Holden – on the series opener, as well as guest judge Carmen Electra who joined the London auditions while Amanda Holden was in hospital.

And the stand-out acts of the night included singing duo Charlotte and Jonathan – aka 16-year-old pop singer Charlotte Jaconelli and 17-year-old opera singer Jonathan Antoine – who wowed the judges at the end of a string of sub-standard auditions.

Their audition has already invited comparisons to Susan Boyle’s original audition after shy, overweight Jonathan took Simon Cowell by surprise.

“Charlotte, you’re good,” he told the pair, “but you Jonathan are unbelievable. You have an outstanding voice.

His attempts to split the pair up came to no avail when Jonathan told him they “came as a duo and would stay as a duo” but eventually he relented and along with the other judges sent them unanimously through to the next round.

Others making an impact included 19-year-old Sam Kelly from Norfolk, who impressed the panel with an acoustic rendition of Adele’s Make You Feel My Love.

“I don’t know what it was but I’ve never felt quite so moved,” Amanda told him, while David added, “I think when you tackle a song like that it’s not just your voice, it’s the way you make us believe you’ve lived every line of that song…I was completely blown away.”

And male dance duo the Sugar Dandies also fared well, making it through to the next round after impressing the judges with their ballroom prowess.

Soran and Bradley – who have been together for 16 years – were described by David as “truly moving” while Alesha was also impressed. “That was a real love story, I just fell in love with you,” she said. “You dance beautifully together.”

And Welsh choir Only Boys Aloud – whose members are aged between 14 and 19 – moved Amanda to tears with their performance.

“I found that really moving – you brought a lump to my throat and a tear to my eye,” she told them, and Simon agreed. “I have got a very very good feeling about you lot,” he said. “I really really loved what you did.”

Meanwhile German-born Dennis Egel left the panel divided after he performed Evanescence’s chart-topper Bring Me To Life, dressed in a gold outfit complete with wings.

Despite Ant running on stage to his rescue after one of the wings fell off, he still scraped through to the next round, with Simon calling him “barking mad” and adding, “that was arguably one of the craziest things I have ever ever seen in my life”.

Other acts totally failed to impress the panel however, with dance duo Two of a Kind and solo dancer Mylene both falling flat – while David described rollerskating duo Skate of Mind as ‘horrible’.

However he loved eccentric poet Barbara and her dancing partner Bradley, even though they left the rest of the panel flabbergasted.

“You have created a new genre of performance – dancetry,” he said. “I want to see it again.”

Simon, on the other hand, was more disparaging. “I will combine it in a differenc way,” he said, “It was pance. I do not want to see it again.”

The auditions will continue on next Saturday night’s show.
