'Infinite Challenge' members apologized for the cancellation of 'Super 7 Concert'.

Yesterday, in various online community forums, pictures from Leessang's concert held on the 28th were shown.

In the revealed pictures, 'Infinite Challenge' members Yoo Jae Suk, Jung Joon Ha, Jung Hyung Don, and No Hong Chul are standing as surprise guests. On this day, they were in charge of the ending stage in their outfits for 'What You Speak' and 'Gangnam Style'.

With unique outfits on, the four bowed in apology for the cancellation of 'Super 7 Concert,' which has recently been a big issue for the show and at one point it led to talks of Gil and Gae Ri quitting the entertainment shows that they were starring in.
