New Kids on the Block & Backstreet Boys (NKOTBSB Tour) July 13, 2011

Then they knocked it out of the park in November when they closed the American Music Awards with a medley that included Backstreet's "I Want It That Way" and NKOTB's "Hangin' Tough." The tour will feature appearances by all but one of the groups' original members: Joey McIntyre, AJ McLean, Jordan Knight, Howie Dorough, Jonathan Knight, Donnie Wahlberg, Brian Littrell, Danny Wood and Nick Carter (BSB's Kevin Richardson left the group in 2006).
