All Together Now

The first episode features interpretations of classics such as 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 the musical theatre with All That Jazz from Chicago and One Night Only from Dreamgirls.

In this second episode, there is something for everyone as a whole range of acts attempts to impress the 100. There are recent hits including Sam Smith's Stay With Me and Walk the Moon's Shut Up and Dance. Three very different duos take on three very different songs: the classic Sinatra standard That's Life, Clean Bandit's Rather Be, and an interpretation of Nirvana's Smells Like Teen Spirit.

In this third episode, a mix of acts must face the daunting task of performing in front of the 100, hopefully getting them up on their feet singing along. This week's show includes a whole host of crowd-pleasers including recent hits such as Sia's Chandelier and Great Big World's Say Something.

In this fourth episode, a mix of talented singers take to the stage to perform in front of the 100 - a 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.

The acts are competing for the remaining two places in next week's grand final. Host Rob Beckett introduces many memorable performances, including a stunning rendition of John Legend's Ordinary People and the classic singalong favourite (I've Had) The Time of My Life from the hugely popular movie Dirty Dancing.

Rob Beckett hosts the grand final as the ten finalists compete to be crowned champion. Whoever wins the title also takes home a life-changing 50,000 prize. The finalists each perform a song hoping to get Spice Girl Geri Horner and as many members of the 100 up on their feet joining in.
