The fourth week of The X Factor 2009’s search for a singing superstar has seen auditions travel to Glasgow, Birmingham and London.

And there were a few surprises awaiting the judges at the auditions north of the border – kicking off with All That Jazz, a duo consisting of Diana Watson and her pet dog Jazz.

However despite Diana’s assurances that her canine companion could “sing very well” she barely uttered a note during her owner’s rendition of I Will Survive – leaving the judges despairing.

“Your dog doesn’t sing does it?” Simon asked. “It’s just you holding her and singing badly.”

And the disasters just kept on coming, including Gisela Lee who blamed her poor vocals on jet lag and Argentinian hopeful Carla Schettini who failed to land a place at bootcamp despite presenting Louis with a tartan tie as a present.

“I actually can’t do this job any more,” barked an exasperated Simon. Fortunately some respite came in the shape of Rikki Loney, who was back for his second attempt at X Factor glory after failing to make it past bootcamp last year.

His performance of the Otis Redding classic These Arms Of Mine had the audience on their feet – and even left Simon admitting they may have made a mistake in letting him go.

“You could be Scotland’s highest hope in the competition this year,” he told an emotional Rikki as he was voted through to bootcamp once again.

The success stories continued in London, with girl singers Shanna Goodhead and Lydia Kabasele sailing through to the next stage, along with girl group The Secrets.

Also making it through was one of the oldest contestants so far this year – 82-year-old crooner William Hooper. Simon remained unconvinced by the pensioner’s voice following his rendition of Come Fly With Me – but everybody else loved it.

“You’re a born entertainer,” Louis told him. “I hope I look like you when I’m 82.”

In Birmingham there was disappointment for 17-year-old Demi Cullum, who failed to make it through despite her enthusiasm.

The teenager broke down on stage after being rejected by the judges – and Cheryl took to the stage to give her a consoling hug.

However the best was saved till last in London – as 25-year-old Essex boy Olly Murs took to the stage and wowed both judges and audience with his rendition of The X Factor‘s Superstition.

“You’ve got the whole package,” Dannii said while Simon told him, “This is the easiest yes I’ve ever given.”

Next week sees a double bill of shows – on Saturday and Sunday – to bring the audition stage of the series to a close.
