The four remaining choirs perform live in the studio tonight, all desperate to secure a place in next week's grand finale and, ultimately, to be declared the Last Choir Standing. From the 60 choirs that auditioned at Cadogan Hall, only the best now remain and they have to impress both the judges and the viewers at home if they are to progress further. One choir will be waving goodbye to the competition tonight, while the remaining three will battle it out again in next week's final show.

Myleene Klass and Nick Knowles host, with judges Russell Watson, Sharon D Clarke and Suzi Digby.

Viewers can vote for their favourite choir after the main show. In the results show later on, the two choirs with the most votes will automatically progress to the live final. The two remaining choirs will perform again. The judges will then decide which choir deserves to reach the final, and which choir will be going home.
