Idol group TEEN TOP left a spectacular impression on the latest 'Immortal Song 2'.

On the April 6th episode, the group combined vocals and performance for their rendition of "My Heart's Jewelry Box" by Sunflower.

Before their performance, TEEN TOP stated, "Since we're idols, we thought we should show dance and performance, so we prepared in that manner. The lyrics were difficult to understand, but the story seems similar to our debut song 'Clap'. That's why we were able to understand it and express it in TEEN TOP's way, so look forward to it."

They impressed the audience, but in the end, 4men took the final win.
