The auditions begin, and only the very worst singers can go through. Carrie Grant is shocked when people who can sing well audition for the show, while those who have always been told that they can't sing have their dreams come true, by making it through to the next round.
The Singers begin their singing lessons with mixed results. Things start well in Liverpool, but the Cardiff group barely get past the first note, and the London group rebel against their teacher. Will the London group be able to stay focussed long enough to learn anything? Meanwhile, the Birmingham group are concerned when their teacher spends more time teaching them about the mind than how to sing, and the Cardiff teacher is beginning to lose faith in her students.
The first group of Singers perform in front of an audience for the first time. The vocal coaching steps up a gear, and there are tantrums as a result. The London group's class joker turns up to a lesson drunk, and Daniel is not happy. Will the Can't Sing Singers be able to beat the odds and become Can Sing Singers in time for the live final?
Cardiff triumph when they sing Delilah to 75,000 people at the Millennium Stadium, but Birmingham falls to bits at Selfridges, and there are tears and tantrums from the London singers.
The Can't Sing Singers reach the end of their vocal journey in tonight's live final. The four groups from Cardiff, Birmingham, London and Liverpool perform Christmas pop hits watched over by David and Carrie Grant, and the nation gets to vote which group of Can't Sing Singers has become Can Sing Singers.
