The second week of Britain’s Got Talent has seen some of the more weird and wonderful auditions from Cardiff and Birmingham.

And following in the footsteps of last week’s successful acts, who included singer Susan Boyle and dance troupe Flawless, Simon Cowell, Amanda Holden and Piers Morgan found plenty more to get excited about this week.

Among those making it through to the next round was 12-year-old schoolboy singer Shaheen Jafargholi, who amazed the panel with his version of Michael Jackson‘s Who’s Loving You.

“This is how one song can change your life,” Cowell told him. “This may be the start of something special for you.”

Amanda, meanwhile, told him that he had passed the “goosebump test”.

“I got them with Paul Potts, I got them with George Sampson, and I got them with you,” she said.

Also impressing the judges was saxophone player Julian Smith, who reduced Amanda to tears with his rendition of Somewhere from the musical West Side Story.

“That was stunning,” she said, “and to cry at a saxophone was something I was not expecting.”

“It was a beautiful choice of music,” Simon added, “and you played it brilliantly. I think there may be something special about you.”

Other acts divided the judges – such as Mamma Trish, the alter ego of entertainer Peter Coghlan – who had the panel and audience cheering and squirming with his decidedly jiggly belly dance.

Simon was not impressed, calling the act “the lowest form of entertainment”, but Piers had other ideas. “We are looking for a big talent and they don’t come much bigger than you – I found you weirdly hypnotic.”

Also splitting the verdict was Phillip Farrugia aka Darth Jackson, who showed off his moonwalking skills while dressed as Star Wars villain Darth Vader.

Once again, Simon was critical. “The act is ridiculous. It’s you, a children’s light sabre and a very stupid mask,” he complained.

Piers and Amanda, however, voted the post office worker through to the next round. “I like your passion for it, I like your determination and you can dance!” Piers told him.

And as per usual, a string of acts flopped badly. Student singing trio Singing Souls hit back with a stream of abuse when Simon said they sounded like “three cats being dragged up the motorway”,

And it wasn’t a good night for animal acts either. Canine performance act Paws For Thought were given short shrift after failing to persuade their dogs to jump through blazing hoops of fire, while Clair and her pooch Carriad failed to emulate former finalists Kate and Gin with their own doggy tricks.

And former bus driver Louise Moores made a swift exit after attempting to perform an act in which her pet parrot Happy Harry repeated song lyrics after she had sung them. Despite her best efforts with the A-ha hit Take On Me, Harry refused to utter a word – and Louise left the stage before the judges even had a chance to comment.
