Toby Keith and Darryl Worley performed for military families at MacDill Air Force Base in Tampa, Fla., yesterday per President Bush's request.

Bush missed the show, however, saying "one of the problems with being the president is you always end up being the last guy here." Nevertheless, he thanked them "for providing (their) talents in support of our efforts to make the world a more peaceful place."

MacDill is the home base for Central Command where all the Iraq war planning takes place.

"If Darryl Worley, Toby Keith and the Star-Spangled Banner can't get your blood boiling, you're at the wrong place," General Michael DeLong, Deputy Commander of the U.S. Central Command, said to cheers.

Worley and Keith aren't the only country stars boosting soldier morale through song. Travis Tritt will visit with the troops and families of the 24th Infantry Division at Fort Riley, Mo., on Friday.

The show, part of his "Spirit of America" tour, is one of several stops he plans on making at military bases across the country.
