I first saw this on Facebook, and I want to share it in case you haven't seen it.
It is beautiful and touching.
The Facebook link came originally from Jim Daly of Focus on the Family.
I would like to quote from Mr. Daly's blog, as he says it so well:
The simple words of love after a life well-lived touched the core of the younger men and women running the contest at the studio. They recorded Fred’s song with professional musicians. In the video, you have an opportunity to listen to the song for the first time along with Fred – and it will be difficult to keep the tears from flowing.
