Boy band pioneers New Kids on the Block are back. Or the group with the most clumsy acronym, NKOTB,  is back. Do people want to see middle-aged men performing boy band songs? We'll see on Friday when all five members - Danny Wood, Donnie Wahlberg, Joey McIntyre, Jordan Knight, Joe McIntyre - will perform on the Today Show. The group returns on the 20th anniversary of the release of "Hangin' Tough." There are also rumors of a New? Kids reunion tour. [People]
