This may be the most beautiful love song you'll ever hear.

An 86-year-old Utah man in the hospital battling a blood infection wanted to show his wife of 66 years how much he loved her, so he decided to belt out a touching version of 'You Are My Sunshine.'

James Pinegar has some moments when the emotions get to him and his wife, Colleen, chimes in with him in this unbelievably heartwarming video, which was shot back in February.

The story has a happy ending, too: James managed to bounce back and is in good health today.
