Caroline and Olly present the first of this year's live shows. The 12 remaining acts compete for the chance to make it through to the live final later this year, hoping to impress the judges enough to stay on the show. Simon has the Overs, Cheryl the Groups, Nick the Boys, and Rita the Girls. However, the standard is high, which is sure to cause drama and disagreements among the judges, and tomorrow's show will see the first act eliminated after a sing-off.
