The first three episodes featured Five , Liberty X , Atomic Kitten , 911 , Honeyz and B When asked why they chose to join the comeback gig , Blue said : " Phil Mount , '' The Big Reunion '' s producer , has always been a long time supporter of the band , giving us our first TV break , he really wanted us to be surprise special guests announced halfway through the series and to perform on the Hammersmith Apollo show . This sounded like a lot of fun , giving us the perfect chance to perform together again in the UK for our fans and reconnect with the other acts , many of whom friends of ours and started out around the same time as us . For us the ' Big Reunion ' is a great chance for all of us bands to come together for one BIG party on Tuesday night ! " Reaction to Blue joining '' The Big Reunion '' was initially negative among the other groups , as well as fans of the show , due to the fact that , unlike them , Blue were not reuniting , having already been back together since 2011 and represented the United Kingdom in the Eurovision Song Contest 2011
