New musical duo, December, which is currently promoting its single Sarang Cham� off the album, "Dear My Lover" is embroiled in a lip-synching controversy. December had their first debut performance on the November 6th's airing of KBS Music Bank, only to be met with harsh criticism from netizens, who went to the Music Bank message boards to express their disapproval. Comments included, "They were suppose to be the new Brown Eyes� If you are going to lip-sync, at least do it right," and "I was excited to see their debut performance and almost fell for their lip-synching because their acting was good. I felt like I was watching "Two Hundred Pounds of Beauty' and wouldn't have been surprised if someone else was singing for them behind the stage." In reaction to the criticism from the netizens, fans of December have come to their defense. In December's official fan caf� site, Der12, members who went to see the taping of Music Bank wrote, "The performance was previously recorded and they performed the song twice, both times live. We actually heard them sing live and cheered them on. The reason they look like they were lip-synching is because footages from both performances have been poorly clipped into one. They sang live 100%." December's management company CS Happy Entertainment also came to the group's defense, stating, "December has never lip-synced their performance before. They've trained for a very long time to get to where they are today and make it a point to always sing live. Misunderstanding may have resulted from poor editing of their debut performance but their future performances will show their capability as singers."
