"IU, Yesung, and Jonghyun will be leaving 'Immortal Song 2' due to their personal schedules. IU's involvement ended with last week's broadcast, while Yesung and Jonghyun's participation will be ending with the June 18th broadcast, the third episode."

"I'm sad that we won't be able to show the original members' development due to the member changes, however, I'm trying to think optimistically about the fact that more idol stars will be given the opportunity in upcoming episodes and that we have a fluid cast in place. This is inevitable because of their busy schedules and overseas commitments."

"Yoseob has an upcoming schedule with B2ST in Japan and his participation is currently under review, but we have already lined up MBLAQ's G.O to come in should he fail to make it for recording. Also on our list are f(x)'s Luna and miss A's Min. We are not discounting rookie group members as long as they fit the requirements that our producers are looking for and have outstanding skills. But as always, it will remain a 6-member cast at all times."
