Following T-ara's Jiyeon's apology on Twitter yesterday, the producers of MBC's 'Music Core' made a formal apology post through their message board on June 26th. The post read:

"Hello, this is the production team for Show! Music Core. We would like to apologize for disturbing viewers with an audio error during the live broadcast of Show! Music Core.�While F.T. Island was performing 'Hello Hello', the voice of our MC introducing the next performer went out live.�As it is a live broadcast, the MCs usually practice their lines during performances, and we believe that this was the case this time. This is 100% the mistake of the producers, and we promise to work hard so that this mistake does not occur again.�We will make sure that we create a better show. To all of the viewers that love Show! Music Core, we would like to once again apologize for the mistake. We will work hard to become a better Music Core. - From the production team of Show! Music Core-"
