MBC's "Radio Star" called musician stars to its holiday party.

"Radio Star" will have a "Singer's Holiday Party" special for its December 11th broadcast, and musician stars such as Yoon Do Hyun, Lena Park, Bobby Kim, and Yiruma will star as guests on the show.

The last time Bobby Kim appeared on the show, he came up with a new entertainment character nicknamed "Angry Bobby". He brought on laughter from the viewers with this new character.

Bobby Kim is close to Yoon Do Hyun, and rumor has it that he advised Yoon Do Hyun, "Don't pretend, and just act as you usually do." Yoon Do Hyun was flustered at his repetition of the same advice. Their friendship and interaction will be one of the high points of the show, as they put on a friendly battle with their words.

The recording was carried out in a holiday party concept. The MCs, as well as the guests, showed up in tuxedos and dresses, and put on a show that is worthy of something like a concert.
