BEAST Yong Junhyung & Yang Yoseob launched a special letter for the fans.

Yong Junhyung and Yang Yoseob who are currently doing activities as a unit performed 'Thanks to' on January 7th PM in KBS 2TV 'Music Bank'(MC Hyunwoo, Kim Minji) live broadcast located in Seoul Yeouido KBS New Wing Public Hall.

'Thanks to' was a unit song revealed on December 12, 2010 on BEAST's first solo concert. Before going on the stage, Yang Yoseob and Yong Junhyung met an editor in the waiting room and said "We never knew we will be performing in music programs with this song" and "If we knew, we should have been more devoted to making the song."

Yong Junhyung and Yang Yoseob presented another charm with their duet unit song different from BEAST. Yang Yoseob's high tone vocal and Yong Junhyung's low tone rap presented exquisite harmony, making the fans flutter.

On the other hand, on this day's 'Music Bank', TVXQ and Secret, Joo, Infinite came back and girl groups Dal Shabet and Piggy Dolls debuted. In addition, First, Kil Hakmi, Kim Baksa, Sunny Side, Tim, F.Cuz, Orange Caramel, T-ARA, BEAST Yong Junhyung & Yang Yoseob and IU performed.
