Ulala Session will be returning to perform on 'Immortal Song 2' for the first time since the passing of their leader Lim Yoon Taek.

Ulala Company stated, "It is confirmed that Ulala Session will perform on 'Immortal Song'. Their possible featuring on the Lee Seung Chul special was discussed since several months ago. The song chosen and choreography are also filled with a lot of Lim Yoon Taek's own ideas. There have been a lot of happenings during that time but since Ulala Session received even more love through 'Immortal Song', they readily decided to perform on the show."

This upcoming special will be Ulala Session's first time on the show in eight months and will be their first stage without their beloved leader. The recording for the episode will take place on May 6th.
