[All] Lee Chan-won's smile ignites Kim Soo-chan's confidence... "I'm S-class," he says, boasting his voice impersonation.

In Immortal Song, Suchan-nim exuded confidence by saying “I’m S-class” while imitating Seol Woon-do’s voice. The atmosphere on set must have been really lively. I can also imagine Chan-won-nim smiling next to him.
As expected from the 44th anniversary special of Seol Woon Do's debut, it was a stage that captured both humor and talent... I believe in trot variety shows.
