INFINITE's leader Sunggyu stole the heart of veteran singer Lee Sang Eun on 'Immortal Song 2'.

During the recent filming for KBS 2TV's 'Immortal Song 2 - Lee Sang Woo & Lee Sang Eun', Sunggyu put on an impressive performance of Lee Sang Eun's past hit, "Dam Da Di".

Before he stood on stage, the singer, who achieved his first win last week, remarked, "My goal is to win twice this week," displaying his determination and confidence.

Stepping out wearing a fedora as Lee Sang Eun often did, Sunggyu looked rather comfortable on stage and led the audience to sing the classic along with him.

The singer flashed his famous "eye smile" and successfully completed his fresh and vibrant "Dam Da Di" stage, earning praise from Lee Sang Eun who complimented Sunggyu, saying "I think I saw a set of three adorable charms: voice, dance, and appearance."

The episode airs August 11th at 6:15PM!
