Darius Rucker and Straight No Chaser are also slated to help ring in the holidays during the fifth annual concert event, set to air Dec. 17.

Dr. Phil and Robin McGraw have been named hosts of the event for the fifth consecutive year. The concert will be taped at the National Building Museum.

Annually attended by Washington luminaries including President George W. Bush and first lady Laura Bush, the holiday music event benefits the National Children's Medical Center, Michael Wright, senior vice president in charge of the content creation group for TNT, TBS and TCM, said in a statement.

"This year's slate of performers is guaranteed to make the 2008 edition of 'Christmas in Washington,' a holiday treat the whole family can enjoy," Wright said.
