The Semi-Final

With all of his workplace choirs set up, the contest to find Gareth Malone's best workplace choir begins in earnest as all four choirs compete against each other for the first time. Each choir is given a new song and Gareth piles on the pressure by announcing that they must create a distinctive performance routine if they want to stand out. Each choir has less than four weeks to prepare, before they must perform in front of the three expert judges at Bristol's prestigious Colston Hall.
