Update: You can watch the video performance here. 5-member group Big Bang and singer/comedian HaHa will be performing a new dance called "Ah, It's Cold" on January 25th at 6pm on KBS 2TV's "Music Bank - Special Stage." The boy band and solo rapper will also be performing each other's songs, "Last Goodbye" and "You're My Destiny." In order to perform a flawless performance, the two teams, despite their busy schedules, have been practicing vigorously together. "Practices have been peaceful and the atmosphere of the room has been filled with so much laughter," a spokesperson from Big Bang's label YG Entertainment had said. "HaHa has always looked after the members of Big Bang, and the boys have always thought of HaHa as an older brother." "We are also hoping that this dual performance will spark the interests of fans, just like it did when Big Bang performed with the Wonder Girls last year," the spokesperson also said. One of the special reasons why these two groups will be performing together, is due to winning first place on Music Bank's K-Chart. Big Bang was awarded the number one spot on January 11th, with their song "Last Goodbye." HaHa was awarded a week later for his song "You're My Destiny."
