Last week, we reported that JYJ would perform for the closing ceremony of the '2011 Daegu World Athletics Championships' on September 4th. Fans had expressed their anticipation in seeing JYJ perform live on TV, but at that time, a KBS official had commented that it was uncertain if JYJ's performance would be broadcasted on air. So you can imagine the relief and excitement fans felt when JYJ's performance did indeed air! Proudly standing on stage as the representatives of Korea during the event, JYJ sang their hearts out with their song "Empty" as beautiful fireworks lit up the night sky of Daegu above them. Check out the video of their performance below! http://www.youtube.com/watch?v=u4VOMDKrThM Source: TV Daily via Nate
