Pentagon brought out their playful yet powerful side on 'Immortal Song'.

On the March 19th special dedicated to Kim Chang Wan, who's an actor and vocalist for 1970s rock group Sanulrim, Pentagon covered Sanulrim's 1979 song "Rascal". The group expressed, "We've appeared on the show multiple times, but we haven't gotten a win yet." 

Kim Chang Wan stood up for the performance and commented, "It was like you were in zero gravity when you danced. It was really fun to watch you looking weightless."

However, Pentagon lost the round, and it was Lee Seung Yoon who took the final win this episode. Watch Pentagon's 'Immortal Song' above, and let us know what you think in the comments below.
