The battle for the crown continues as the eight remaining acts step onto Britain's biggest stage for the fifth live show. Each of the performers will be hoping to impress the voting audience at home as well as judges Simon Cowell, Cheryl Cole, Dannii Minogue and Louis Walsh. Host Dermot O'Leary will be on hand to deal with the war of words as the judges give their views on each performance and defend their singers. Next time, one act will be leaving the competition.
