I just heard that song the other day, I loved it. It got me quite choked up as well. I love those type of songs. I love Honey by Bobby Goldsburo, The Deck of Cards, Phantom 309 by Red Sovine, and Teddy Bear... all those songs bring a tear to my eye.
THey had a Billy Ray Cyrus "Personal Playback," and although I'm not that fond of him, I DID see the beginning. He was talking about the making of "All Gave Some. Some Gave All."
