Just another day at the office? Not exactly. Patients and staff at Children's Hospital at Dartmouth Pediatric took the time to create a video that will warm your heart. Watch as young and old perform Katy Perry's 'Roar' throughout the hospital.
Remember a few weeks ago when Katy Perry announced on GMA that she would be visiting one high school on her birthday for a very special performance in conjunction with the release of her new album, Prism? One high school created their own version of 'Roar,' and you've got to see this.
