The newly released movie "We Were Soldiers" has a song, part of the lyrics being "lay me doon on the caul, caul groon, where afore many mair have gone." It was very scottish. Looking at the soundtrack listing there is a song called Sgt. Mackenzie by a Joseph Kilna Mackenzie and I could only get an excerpt from that song which had just bagpipes in it. It seemed to be the same song though. I would like to no more about this song, the artist, the writer, the lyrics, the history etc. It was very evocative and very sad.
