Earlier this week, we reported that IU and Jung Yeop would be singing a Christmas carol on a Christmas special on December 18th for MBC's 'A Concert for Beautiful People'. This early pre-Christmas special has aired today and you can now catch them harmonizing perfectly during their performance for "Blessings on Christmas", which was complemented by the delicate sounds of a full 50-membered chamber orchestra. There were also other performances on from this special show, and you can now watch them below to get yourself into the Christmas mood!
