In this first episode, we have a huge musical variety on show, so there's something for everyone. We'll see interpretations of iconic all-time classics, 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. Some of the acts try their hand at musical theatre with All That Jazz from Chicago and One Night Only from Dreamgirls both featuring. There's 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.

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. There are several memorable interpretations of classic songs: Oasis' Don't Look Back in Anger; Whitney Houston's I Wanna Dance with Somebody, and a 1920s take on The Eurythmics Sweet Dreams.
