Kangin, who is currently serving the Korean military, has made a surprise appearance on Super Junior's concert through a video. On the 15th, Super Junior held their concert, Super Show 3, at Seoul's Olympic Park. Before their concert, the active members held a press interview and revealed, "Even though Kangin is serving in the military, he will be making a surprise appearance. It has been planned for Kangin to perform Handel's opera, Rinaldo, with us, but our hearts still ache. We wish he were there instead of just his voice." As revealed, Kangin joined the members during their opera performance of Handel's Rinaldo and performed an orchestra version of Lascia ch'io pianga. Since he couldn't personally be there for the concert, Kangin made an appearance through a pre-recorded video and made a heartwarming performance which delighted the 10,000 fans who were present. This Seoul concert marked the official beginning of their Asia tour. On another note, fellow member Kangin was not the only special guest at this concert. Although he wasn't there to perform, 2PM's Nichkhun was at the concert to cheer on his buddies. Super Junior's Shindong was the one to reveal this fact through his Twitter account. On the 14th, he uploaded a picture of Nichkhun posing with Super Junior members Yesung, Ryeowook, and Donghae, and tweeted, "Khunnie arrived!!! Concert's starting hehehe Super Show 3 go go go!!!!"
