It was another tension-laden week for the The X Factor finalists after they performed Queen and Lady Gaga songs on Saturday night’s show.

And this time things were further complicated by the addition of the public vote to bring one of the previously rejected finalists back, following Frankie Cocozza’s departure.

The public were given the option to vote Amelia Lily, 2 Shoes, Jonjo Kerr or James Michael into the competition – with Amelia revealed as the choice of the viewers on Saturday’s show.

The programme also began 15 minutes late after a technical fault forced it off the air.

Viewers were told that the production was experiencing difficulties while a reel of audition footage from earlier in the series was played.

When it eventually began the first act to take to the stage was Kitty Brucknell, singing Queen’s Don’t Stop Me Now.

The judges approved of her song, with Kelly saying, “This was a really fun performance,” and Tulisa adding, “I know you didn’t get the song you wanted but you don’t know how this suited you down to a tee.”

Craig Colton – who had reportedly had a difficult week after threatening to leave the show – turned in a performance of Lady Gaga’s Paparazzi that won rave reviews from the judges.

“That for me was the best performance you have ever done,” Tulisa told the 23-year-old, while Louis described his song choice as “brilliant”.

Little Mix, meanwhile, received a mixed response from the panel for their mash-up of Lady Gaga’s Telephone and Queen’s Radio Gaga.

Louis told them they had a “big future” but Gary added, “I’m a little bit disappointed in you tonight, it feels like you’re running out of ideas for these girls.”

He was similarly disparaging about Janet Devlin, who perfortmed a pared down rendition of the Queen classic Somebody To Love.

“I hate to say this but I’m starting to lose interest in you,” he complained. “That performance didn’t work tonight.” Louis, however, disagreed, saying “I can see you in the final.”

Marcus Collins and Misha B, however, won rave reviews from the panel – Marcus performing Queen’s Another One Bites The Dust and Misha taking on Lady Gaga’s recent chart-topper Born This Way.

“I thought this was a really good week for you,” Kelly said of Marcus’ performance while his mentor Gary added, “We are in the presence of a pop star – well done.”

And the Take That frontman described Misha as a “class act” while her mentor Kelly added, “Manchester, you need to pick up the phone and vote for your own.”

Finally Amelia Lily had her moment in the spotlight, singing the Queen hit The Show Must Go On – and her comeback was worth the wait.

“You must be in shock,” Tulisa said, “but you really deserve to be here because I know how much you want it.” And Louis added, “Welcome back – I think you’re really talented and I want you to go far in the competition.”

The results will be revealed on Sunday evening’s show, which will also feature a performance from Lady Gaga.
