This is one of the New England's Children Hospitals performing a rendition of Katy Perry's ROAR!
This is such a great heartwarming video where the WHOLE staff of CHAD seems to have gotten involved!
For some of these kid's they are going through the worst part of their lives, they are fighting to stay alive. These children are amazing people already and will hopefully continue to touch others through out their lives!
This is what CHAD'd website has said:
The world is indeed a very good place filled with many caring and compassionate people who care deeply for each other.
