Summary: 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.
