Country musician Trace Adkins entertains Sailors aboard USS Abraham Lincoln during a USO-sponsored concert held in the ship?s hangar bay. Sailors took advantage of the opportunity to meet Mr. Adkins ?up close and personal,? for photo opportunities and personalized autographs. For more than sixty years the USO has brought entertainment and comfort to U.S. service men and women around the world, in conflicts from World War II to today's Operation Enduring Freedom. There is hardly a name in the list of entertainment and sports celebrities that hasn't appeared on a USO show roster of those entertaining the troops these past six decades. Abraham Lincoln is on a regularly scheduled deployment in support of Operations Southern Watch and Enduring Freedom. U.S. Navy photo by Photographer's Mate Airman Stephen Neel.
