"JackRyurl! JungShin TongIl" (Burst! Mental Concentration) episode aired 5-19-2007 had Eun Ji Won (Sechskies) and Tony An (H.O.T). It has been a while since members from the rival groups had been on a show together.
These cuts are the preview from the previous show, the Ji Won and Tony parts of the posing through the wall game, and the previews for the next show.
I love the way they play Sechskies and H.O.T songs. Brings back good times.
