The July 12 episode of the idol show featured Yoon Jong Shin and his ''slaves'' or artists under his label.
During the talk, Jung Hyung Don revealed that he was a huge fan of Yoon Jong Shin's songs. He reminisced the old days and said, "There's a song titled 'Girl on the Second Floor'. I really loved that song."
He then requested Yoon Jong Shin to sing the song live at the studio. Yoon Jong Shin happily accepted his request and sang for the MC.
After the performance, Jung Hyung Don surprised all by showing tears. Defconn pointed out that it's the first time Jung Hyung Don has ever cried on 'Weekly Idol' and commented that the song must be bringing back old memories for Doni.
Yoon Jong Shin lightened up the mood as he jokingly commented, ''This is just what happens when you meet a celebrity.''
