Background

During the summer of 2010, the Backstreet Boys joined New Kids on the Block onstage at the Radio City Music Hall, where the groups performed "I Want It That Way". Since the performance, the media began to circulate rumors of the two uniting for a tour in the summer of 2011.
The tour was officially announced on On Air with Ryan Seacrest during an interview, where it was mentioned the groups were recording a single to be later released. To promote the tour further, the groups conducted a live Q&A session on Ustream. The groups also performed at the 38th Annual American Music Awards to give the public a taste of what they would see on the tour. For an interview on Entertainment Tonight, Donnie Wahlberg held a picture of the proposed staging, which featured a standard concert stage with an extended catwalk leading to a circular platform.
