Gareth Malone launches his exciting singing contest to find Britain's most entertaining amateur choir. This week, Gareth is looking for a group to represent Wales and the Midlands. His audition tour features a Leicester gospel group, a Telford community choir led by the local vicar, singing students from Nottingham and an all-female choir from a Welsh mining town, plus an eyebrow-raising surprise at a countryside garden party. But who will Gareth bring back to the sing-off? And will his chosen choir rise to the challenge of a public performance in their home town?
