The kids of St. Jude Children's Research Hospital have prepared a special treat for some of the program's supporters and donors: a heartwarming rendition of "Carol Of The Bells."
The video states:
Because you gave them a chance at life, the kids of St Jude created this special holiday gift for you.
The mixed look of pure concentration and utter joy radiating from each child's face makes it hard not to smile as the children chime along to an instrumental version of the classic holiday tune.
St. Jude research hospital treats about 7,800 active patients with cancer and other diseases each year, according its official website.
