A star-studded celebrity special of the entertainment show set to get the nation up on their feet and joining in.

Hosted by comedian Rob Beckett, the programme sees a host of famous faces singing their hearts out in a bid to win over TV's biggest judging panel, the 100. Headed up by Spice Girl Geri Horner, the 100 are a mix of great singers from every corner of the music industry and they are hard to impress!

Facing the 100 in this one-off event are reality star Gemma Collins, football legend Chris Kamara, showbiz presenter Alison Hammond, EastEnders actress Laurie Brett, England rugby star Ben Foden, Love Island winner Amber Davies, comedian and actor Omid Djalili, stand-up comedian Sara Pascoe and actor Tyger Drew-Honey.

The celebs hope to give a show-stopping performance that gets as many of the 100 up on their feet and singing along. The greater the number that join in, the higher the act's score.

Each act has chosen a song they hope will get them into the sing-off at the end of the show. But it is not just the song that counts - it is the performances that matter and these celebrities need to deliver!

There is something for everyone, from ballads to bangers, musical theatre to modern day hits and a whole load of laughs from Rob, Geri and the 100.

At the end of the programme, only one act can be crowned the All Together Now Celebrities Champion and walk away with the trophy. Which of these stars will succeed and get the 100 up on their feet and singing along? Show less
