All Together Now is a unique singing contest that sees ‘The 100’ – a panel of 100 performers and industry professionals with big voices and even bigger opinions – respond to their favourite competitors by standing up and singing along with them. The aim for singers is to get as many of ‘The 100’ diverse voices joining in as possible, which is no easy task! Competitors will be supported by hosts Julia Zemiro and Ronan Keating in the Australian version of this sensational format, which is based on the UK hit of the same name and produced for Seven Network.
