There is nothing quite like music to bring a family together - which is why this video of Kayla Hartman singing for her grandfather is being watched millions of times.

As a means of cheering her ailing father, Hartman and her daughter sang a heartwarming rendition of "Grandpa" by The Judds.

The performance was caught on video, and based on the emotional reactions of the family members, it's not hard to see why it's being shared so widely.

"Being able too get this video is absolutely amazing," says Hartman. "I break down in the middle but he loves every minute of it!"
