On the Yoon Si Nae special of Immortal Song 2, broadcast on September 15th, Top Band winners Toxic made their first appearance on the show. They did so with a Toxic style arrangement of Yoon Si Nae’s “여자의 마음” but lost against Sweet Sorrow‘s updated and energetic version of study campaign song “공부합시다“. In the end MBLAQ’s G.O won the Yoon Si Nae special with his rich ballad version of “사랑의 시“. During the episode 4Men‘s Shin Yong Jae revealed that he was a high school senior of Toxic guitarist Kim Jung Woo.
