Coming back from winning triple crown on Music Bank yesterday, the boys of Super Junior returned on today's episode of Music Core to perform their hit track BONAMANA. Unfortunately, there were still nine boys as Kyuhyun is currently recovering from surgery for tympanitis. So the boys stepped up their talent to another level as they performed a terrific performance of BONAMANA. http://www.youtube.com/watch?v=lVFctmV94JE
