Caroline Redman Lusher is the founder of Rock Choir - the biggest contemporary choir in Britain. And in five months' time they'll be putting on the biggest performance of their lives as they attempt to fill the 10,500-seat Wembley arena.
With a burgeoning repertoire of rock, pop and gospel music under their belts, Rock Choir has something for everyone. And there are no scary X Factor-style auditions to join up -- all you need are your vocal chords and bags of enthusiasm.
With an "anything goes" attitude, it's no wonder the choir has so many devotees all over the country. From teen stars with life-threatening heart conditions to plumbers moonlighting as Rock Choir leaders, you never know who you'll bump into at your local club.
Episode one sees 57 eager Rock Choir members plan their very own flash mob in the middle of a York shopping centre.
But will the locals go wild in the aisles as the Rock Choir sing Dancing In The Street? And will they drum up enough support to fill Wembley?
