Singing contest hosted by Rob Beckett which sees a range of talented singers take to the stage to perform in front of the 100 - a unique panel of music experts and performers from all over the UK. If any of the 100 like what they hear, they can stand up, join in and sing along. The greater the number that join in, the higher the act's score. At the end of the series, one act walks away with a cash prize of £50,000.

Heading up the 100 is pop icon Geri Horner. As a member of the Spice Girls, the best-selling girl group of all time, Geri knows exactly what it takes to get a crowd joining in and singing along.

Each week the acts, which include soloists and groups, amateurs to professionals, aim to make it into the top three. The winner is guaranteed a place in the final, with the acts in second and third each performing another song in a dramatic sing-off. The winner of the sing-off also goes through to the final.

The first episode features interpretations of classics such as like Lionel Richie's All Night Long and Tina Turner's Proud Mary. There are contemporary hits like One Last Time by Ariana Grande and Slow Hands by Niall Horan, and some of the acts try their hand at musical theatre with All That Jazz from Chicago and One Night Only from Dreamgirls. There is even an extraordinary mash-up of opera and rock'n'roll.

The 100 know all the songs but they never know who's performing them so there are surprises every step of the way. Show less
