Gen. Martin Dempsey sings to families of fallen heroes

Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, has some serious musical chops.

Yesterday during an emotional ceremony honoring families of America's fallen heroes, Dempsey uplifted the crowd karaoke-style, singing to Andy Grammer's 'Keep Your Head Up". The event, hosted by TAPS or the Tragedy Assistance Program for Survivors was held in Arlington Virginia.

But Dempsey's performances didn't end there. Right after, he took to visiting children who had also lost their family members in military service, singing animal songs with the Good Grief Camp.
