B.A.P.'s leader Bang Yong Guk will be collaborating with SECRET's Jieun at the '2011 MBC Gayo Daejaejun'! On December 31st, the two will be working together once again for their 2011 hit, "Going Crazy", to commemorate a successful year, as well as look forward to more things to come in 2012. The song ranked at the top for a month in February, and Bang Yong Guk himself earned a lot of praise for his ability to lead on the performances with Ji Eun in a fashion that made it hard to believe he was a rookie. The two will come together to collaborate for the remix version on the stage of the '2011 MBC Gayo Daejaejun'. B.A.P.'s Bang Yong Guk, Zelo, and Himchan have been promoting actively even before their debut. They've been participating on various TV programs as well as in special performances, in addition to their half-time advertisements that were aired during the major year-end ceremonies. The boys are currently preparing for their debut showcase on January 28th.
