Kim Heechul, Song Jihyo and Eun Jiwon will have a surprise appearance on SBS’s Inkigayo.

Inkigayo, which started its first broadcast in the year 1992, will celebrate its 600th episode on the 12th (of December). During a call with Newsen on the 9th (of December), Hwang Inyoung PD, who is in charge of the performances said that: “The special stage will cover three different aspects”.
The first would be the surprise appearance of the past MCs. Kim Heechul, Eun Jiwon and Song Jihyo will show their progress together with the current string of MCs (which are) 2AM’s Jo Kwon, C.N.Blue’s Jung Yonghwa, and f(x)’s Sulli.
The second would be the idol (group) member’s trot medley. 2AM’s Changmin and Jinwoon, SHINee’s Key, Orange Caramel’s Lizzy, Sistar’s Hyorin, T-ARA’s Soyeon – three males and three females in total – would put up a delicious trot stage.
The last one would be a celebratory stage by singers that even the crew does not know about. It is understood that Sistar, T-ARA and Norazo will perform their own congratulatory mission. Each of them will convey their congratulatory messages through a unique performance.
Hwang PD also informed that “Only 4 months was given to arrange the performances for Inkigayo’s 600th episode special,” and that “As we have received a love from the audience for a long time(,) a cool stage will be fabricated”.
On that day, Inkigayo will broadcast its 80-minute special episode from 3:50PM to 5:20PM.
