The final of the competition takes place at Ely Cathedral, Cambridgeshire, where the three remaining choirs perform the world premier of a piece by composer Paul Mealor and lyricist Brendan Graham. Having been practising intensely for six months, the choirs are now challenged by choirmaster Gareth Malone to interpret the piece however they wish, meaning that within each choir, the members must agree on their strengths, their style and their stars. Performances, backed by the Ely Cathedral Choir, take place in a packed cathedral, where the most beautiful choral singing has resonated for a thousand years. It then falls to the three judges to decide who will be crowned best workplace choir.
