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.

Meanwhile, one of the acts comes face to face with head of the 100 Geri Horner as she bravely sings one of Geri's biggest hits It's Raining Men. The other hopefuls perform a huge variety of songs, including the recent hit Galway Girl by Ed Sheeran and 80s classics Goodnight Girl by Wet Wet Wet and Ain't Nobody by Chaka Khan. And just how did the 100 respond when one performer took to the stage to sing the cockney classic Rabbit by Chas n Dave?

The acts, a mix of professionals and amateurs, must win over the 100 and make it into the top three. The winner is guaranteed a place in the final, with the acts in second and third place each performing another great song in a dramatic sing-off. The winner of the sing-off also goes through to the final, where ten acts go head to head, each hoping to win the series and take home £50,000. Show less
