Singers IU and Jung Yeob are scheduled to participate in a collab for a Christmas special coming this December 18th during�MBC's 'A Concert for Beautiful People'. The two harmonized perfectly during the recording of their performance for 'Blessings on Christmas', which was complemented by the delicate sounds of a full 50-membered chamber orchestra, and expectations are unsurprisingly very high. Some spectators in the audience expressed, "It is a really special Christmas carol," "Their voices both sound really sweet and well-suited," and "It felt like a dream, listening to a duet with two of the best singers." IU's performance of her album track�"Merry Christmas in Advanced" is also set to be broadcast on the show. Source: Sports Today
