Huh Gak returned to his school days on 'Immortal Song'.
On part 1 of the 'King of Kings' special on December 14, Huh Gak covered Kim Kwang Suk's 1991 hit "I Loved You But". The singer expressed, "It's a song I sang often during my high school days. I hope the audience feels the feeling and yearning of Huh Gak ballads."
Though Huh Gak put on an emotional performance, it was Forestella who took the final win on part 1 of 'King of Kings'.
