John & Edward 'forced to change song'

X Factor contestants John & Edward have reportedly been forced to change the song they are performing on tonight's show at the last minute.

The teenagers were due to attempt Queen's hit 'Radio Ga Ga', but have been advised to try the band's 1981 collaboration with David Bowie 'Under Pressure' instead, according to The Mirror.

A show insider told the newspaper: "The twins were struggling a bit with 'Radio Ga Ga' so a decision was made to change their song.

"But they're freaking out now as they're having problems remembering the words for 'Under Pressure' and they're worried they'll mess it up.

"For the past few weeks, their performances have been ambitious but there is no big production to hide behind this time.

"There's some big notes in this song too so that's another worry."

Last week, John and Edward were in the bottom two but were saved by the public vote after Simon Cowell decided to go to deadlock.

The twins' mentor Louis Walsh revealed that he will be delighted if the 18-year-olds can survive another week.

He said: "I'm worried about them going home. If we get through I'll be so happy."

The X Factor continues tonight at 8pm on ITV1.
