Mary to sing Dusty track on 'X Factor'

Tesco worker Mary Byrne is to perform a Dusty Springfield classic on this week's X Factor.

Byrne, who won praise from the judges last week for her rendition of James Brown's 'It's A Man's Man's Man's World', will perform the 1966 number one 'You Don't Have To Say You Love Me'.

A source told Ireland's Evening Herald: "Last week was a tough one for everyone because it was the first live show but this week will be even tougher for Mary now that she's shown what she can do.

"Her fans are expecting another brilliant performance from her and to be blown away again by that big voice. It's nearly more important that she does well this weekend as she wants to prove it wasn't just a one-off performance."

The insider continued: "Louis has chosen a great song for her to sing. He just handed her his iPod and told her to listen to it over and over until she had it inside out. As she listened to it they just kept looking at each other, and then Mary started laughing nervously and they nodded to each other - I think they both know this will be amazing, if she can nail it."

The X Factor airs on Saturday at 7.30pm on ITV1.
