Younha and Kim Gun Mo had faced off against each other in a special piano battle at the 32nd Campus Song Festival held yesterday night. Two pianos were placed in the center of the stage as both faced off against each other as they sang while playing the piano. The Wonder Girls then appeared as they sang while Kim Gun Mo played the piano while Bobby Kim did likewise for Younha. They ended the special piano battle by singing another song together. The Wonder Girls must be wearing the same outfits since this afternoon while performing at Music Core and then the 13th PIFF, ending with this. source: wonderland
