Singer Huh Gak put his ballad skills to use on the latest installment of 'Immortal Song 2'.

For the Lee Moon Sae special, he covered the sad, romantic ballad "When Love Passes By". Huh Gak previously covered Lee Moon Sae's songs on 'Superstar K2', and he felt extra nervous about this performance as it's been three years since he's seen the veteran singer.

His rendition blew everyone away, and fellow competitor Kim Tae Woo commented, "I like Huh Gak's style. Remakes have to liven up the original song." Lee Moon Sae also added, "This song has a difficult melody to follow, and you did well."

However, musical star Jung Sung Hwa took the final win.
