Little Big Town will sing at the Library of Congress' Coolidge Auditorium in Washington, D.C., on Dec. 4, as part of the CMA Songwriter Series. The group will be joined by host Bob DiPiero (Tim McGraw's "Southern Voice," George Strait's "Blue Clear Sky") and fellow songwriters Brett James (Carrie Underwood's "Jesus, Take the Wheel," Jason Aldean's "The Truth") and Lori McKenna (Faith Hill's "Stealing Kisses," Sara Evans' "Bible Song"). The concert is free, but a ticket is required and can be obtained through Ticketmaster.
