Hundreds of lip-dub videos are dedicated to covering Katy Perry’s hit song "Roar," with the star promising to perform live at the high school with the best one.
This one is different, though.
It’s not from a school, but it celebrates the meaning behind the #1 song like never before, and Katy Perry would no doubt be proud to have inspired it.
Patients, nurses, doctors, staff and administrators at the Children’s Hospital at Dartmouth-Hitchcock in New Hampshire all assembled for this effort. Watch:
The video, shot in one day, captures almost all the kids at CHaD who were "feeling well enough to get out of bed and dance," according to local media.
Funds raised through sharing of the video will benefit the CHaD Hero Half Marathon. So far, the response has been astounding – upwards of $650,000.
