Secretary of Defense Donald H. Rumsfeld tells the audience about Nashville singer/songwriter Darryl Worley prior to a concert in the center courtyard of the Pentagon on April 16, 2003. One of the songs Worley sang for the military and DoD employee audience at the Pentagon and around the world on American Forces Radio and Television was his hit single "Have You Forgotten." Worley wrote the song after traveling with the United Service Organizations to entertain troops in Afghanistan last December.
