The X Factor, live shows, week four

Joe McElderry opens rock night with a convincing version of Don't Stop Believing.

"I loved seeing you move amongst the audience. You looked so comfortable and they adore you," said Dannii.

Louis agreed, saying: "On paper I didn't think it was going to work but you absolutely won me over. Don't stop believing because you WILL be in the final."

Simon tells Joe he is one of the most consistent performers but adds it was, "a little bit limp and stage school in parts."

Lucie Jones connects with her inner rock chick to sing Sweet Child of Mine.

"You are such a consistent performer in this competition," Louis says, adding: "Simon I think you owe her an apology."

"OK...The reason I didn't like you last week was because you were boring," says Simon. "You're a good singer but you've been made to be old fashioned. Tonight I take that back because you made yourself contemporary."

Cheryl agreed, saying: "Last week you totally won me over... and tonight I thought maybe you could be Avril Lavine. I was really impressed."

Dannii's smile says it all. " I'm so happy and proud!" she beams.

Danyl Johnson sings I Don't Want to Miss a Thing, but being in the bottom two last week has clearly knocked his confidence.

"You've lost your mojo," Dannii tells him, adding: "It was out of tune at the beginning."

Cheryl says: "I'm finding this uncomfortable to be honest. Being in the bottom two last week has obviously dented your confidence."

Simon says: "Here's the problem... If you come out confident, you're cocky and if you tone it down, it's not right... you are still undoubtedly one of the best singers in the competition and I genuinely hope the public vote for you."

Lloyd Daniels takes on I Kissed a Girl, accompanied by a bevy of beautiful dancers.

Dannii tells him. "It was a great performance but your voice was drowned out by the track at times."

Louis says: "You sang a pop song so you cheated."

Simon snaps at Louis, "You've got to stop believing that you create the rules in this competition because you're becoming so boring.

"The vocals in the beginning were bad, but it was a million times better than last week."

Cheryl says: "You're a little popstar... everyone loves you just how you are."

Stacey Solomon is up next, singing Somewhere Only We Know,

"I wasn't crazy about the song choice, it was a bit boring, but I love you," Louis tells her.

Cheryl doesn't agree, saying: "I loved that song choice for you. I would like to see more of your personality in your performance next week though."

Simon is more impressed with her walking than the singing. "It was extraordinary - like an X Factor miracle tonight – you walked!" he said.

Rocker Jamie Archer shows everyone how it's done, performing a rock song - in a rock style.

Dannii tells him: "You're absolutely in your element... you're an amazing performer and singer."

Louis agrees it was a great performance but says it was nothing original. "I've seen 100 guys singing what you do in pubs - you're like a Lenny Kravitz impersonator. You're not a real rocker."

Simon snaps back: "When was the last time you went into a pub Louis?... Of all the performances it was the most authentic. Jamie, you were terrific tonight."

Rachel Adedeji delivers an emotional version of One by U2.

"That was an incredible song choice," Louis tells her. "I didn't think it was a good idea on paper but you made it your own. It was emotional, soulful - in fact I thought it was the most emotional performance of the night."

Cheryl agreed, adding: "It was a very, very clever song choice because you got to show the soul in your voice."

Simon wasn't so keen: "Your whole look and therefore presentation made that song a bit cabaret."

Dannii had the final word, telling Rachel: "It was an amazing performance... you just sang, it was just about your voice."

John and Edward dress like teen vampires to deliver their own take on Queen's We Will Rock You.

"That was quite scary," Dannii tells them. "I think you almost needed a Sat Nav to find your way back to the lyrics. I look forward to seeing you every week, but not sure I would look forward to hearing you on the radio."

Simon tells them: "It was night of the living dead, singing Queen out of tune. I'll credit you with tenacity, you're thick skinned but you cannot, cannot defend that singing tonight Louis.

"These are two young kids living the dream," says Louis. "Nightmare," corrects Simon. Louis continues: "It was energetic, the audience loved it, it was exciting."

Olly Murs closes the show with Come Together - and rips his shirt open at the end.

"I have to say I absolutely adore you," Dannii tells him. "You are hot, hot, hot. The moves get better every week. You're vocals are consistently brilliant."

Louis says: "I think you're the dark horse in the competition. You're the one artist improving more than anyone."

For once Simon agrees with Louis, saying: "You are progressing better than just about everyone right now because you're getting more confidence, you're learning how to perform, you're sounding like an incredible artist. I'm very proud you."
