A friend sent me a link to this very touching song, which was written by Joe Bonsall of the Oak Ridge Boys. It is a tribute to his parents, both of whom served in the military during World War II. He wrote the song in conjunction with his book, G. I. Joe & Lillie: Remembering a Life of Love and Loyalty.
I doubt you will be able to watch the video without shedding a few tears.
I know I couldn't.
