It has been ten years since choirmaster Gareth Malone first set out on a mission to get Britain singing. Since then, he has inspired hundreds of people, creating 14 very different choirs across the country, from schools to entire towns to military wives. Now to mark the 10th anniversary, he has a dream - to track down and bring together all the choirs he has formed for a huge reunion party. As a centrepiece for this party, he wants to put together his choir of choirs, a super-group of the most talented singers he has encountered over the years. He has got just four short weeks. Can he bring them together in time? And can they pull off a performance that is worthy of a decade's work getting the nation singing? As we follow Gareth on his latest mission, we rediscover the characters and stories of ten years of The Choir.
The Choir was broadcast on BBC2 at Sunday 27 March 2016, 19:00. This episode was initially placed on Thursday 31 December 2015.
