Two of the biggest boy bands in pop history, New Kids On The Block & Backstreet Boys, brought their NKOTBSB Tour to the UK on April 28, 2012. The second night on April 29th at the world-famous O2 Arena also set a milestone- the show was broadcast online and in select theaters all over the world via livestream. NKOTBSB first shocked and delighted fans when they took the stage together for a medley at the sold out NKOTB Radio City Music Hall show in 2010. The two groups wowed audiences again in their first t televised performance at the American Music Awards in November 2010 and then went on tour together in 2011 through 2012.
