The second week of X Factor 2011 brought with it a number of unexpected surprises, as auditions travelled to Liverpool’s Echo Arena and the O2 in London.

And among those springing a few surprises in Liverpool was biscuit factory worker Craig Colton, who not only amazed the judges with his powerful rendition of Adele‘s Melt My Heart To Stone but also stunned his parents who were in the audience.

The 22-year-old confessed that he had not told his mum and dad he planned to audition, but instead had booked them tickets for the audition and said he could not attend as he had to work.

They had every reason to be proud of him after Louis Walsh called his audition ‘amazing’.

“We are looking for someone with a recording voice and you have definitely got the recording voice,” he said.

Tulisa, meanwhile, said that she had not expected Craig to be so good and also praised him for his cheery personality. “You are funny as well, I love it,” she told him.

There were more surprises for the judges in London when 45-year-old Johnny Robinson took to the stage.

Johnny, who confessed he lives alone in a bedsit in Harrow, North London, showed an eccentric side to his personality when he asked the backstage staff to help get rid of his wrinkles – but he defied expectations with his rendition of Etta James’ At Last.

Tulisa said that he had the “shock factor” while Gary Barlow added, “I just thought that was an amazing audition, I think you’ve got a fabulous personality.”

Others to make it through to boot camp included 20-year-old Burger King worker Derry Mensah, who admitted that he had a crush on Kelly Rowland – and was rewarded with a hug from the Destiny’s Child singer after he had auditioned.

The judges had some reservations about Derry’s audition, with Louis saying he would fare better “in a boy band” but he added, “You’ve definitely got something!”

Kelly agreed with Louis, but Tulisa told him he was absolutely right to audition as a solo artist while Gary added, “I think you’ve got a really great voice. I really enjoyed that audition…well done.”

Teenager Misha Bryan, meanwhile, wowed the panel with her modern take on Aretha Franklin‘s Respect, which also included a spot of rap.

Tulisa was particularly impressed with the 19-year-old, saying she had given the “best audition of the day” while Gary said, “You know it was fantastic as well, and that kind of confidence we haven’t seen a lot of yet.”

And Samantha Hallam not only made it through at the London auditions with her version of Kings Of Leon’s Sex on Fire, but the 37-year-old also gained herself a fiance after her boyfriend Paul took to the stage after her performance, got down on one knee and proposed.

However it wasn’t such a good night for bands, with several falling flat, including boy-girl outfit The Duos, whose off-key version of Beyonce‘s If I Was A Boy failed to strike a chord with the panel.

Of all the other groups who auditioned, only boyband The Keys really made an impact with an acapella medley of songs.

Louis was full of praise for the five-piece, saying “We’ve been waiting for a group like you guys!”

And Gary was similarly impressed. “Guys, that was magificent, really good,” he said. You’ve individually got great voices and you work as a team.”
