The Marines and sailors, who served in conflicts in Iraq and Afghanistan, have been invited to the Nissan Pavilion show in Bristow as his personal guests.

They're all patients at the National Naval Medical Center and are currently receiving treatment and therapy for their injuries. Some are single leg amputees; others have suffered blast injuries, burns, and traumatic brain injuries.

Kramer says, "I can't think of a better gift to receive on my birthday than to have the privilege of sharing a night of our music with these brave and heroic warriors who have been wounded in the service of our country."
