Glad for the success in finding the right song. I would have suggested "Special Absent Friends" which though different is along similar lines but addressed to many who have gone on before. I have heard the song only by Speed Limit, a country duo from the British Isles, until today when searching youtube for a link to post here. Knowing nothing about the origins of the song I accepted the Speed Limit song as a tribute to those known and loved from earlier times. Some of the youtube videos seemed to have political overtones.
