The New Kids on the Block did a show for our very own iHearRadio this weekend.  But things didn't go well for the group when Jonathan walked off stage. 

John didn't do well from the start when it became obvious he was having trouble.  He didn't join in the hand waving during "Hanging Tough," and he seemed to answer a call, or at least look at his cell phone when it rang during the show.

Fast-forward to 27:00 if you want to see John walk off; and push it to 41:55 to hear the guys joke about the situation.

For the record it's been widely reported that Johnathan suffers from stage fright and anxiety.
