At the 2011 KBS Music Festival that took place at KBS Hall on December 30th, Lee Seung Gi put on a special cover performance of "Passion" & "Na Na Na". The ballad singer displayed a completely different side of himself, showcasing some of his hidden swag wearing a black leather jacket and never missing a step of the choreography.
