The music that fits Byron's Lochnagar sounds 19th Century to me. Of course it could be an arrangement of older tunes. I would like to hear what Malcolm Douglas says about it. The same old lp, The Tartan, sung by Kenneth McKellar, that had Mo Mary (see thread of the last three days) also has Lochnagar. All of these old McKellar renditions are available on an import 2cd Decca set.
