Thanks to all of you. I think it is not easy to find "original" Scottish emigrant songs but there are some "near enough" as "Caledonia" or "The Rovin' Dies Hard" (thanks Susanne for the lyrics) or the Brian-McNeill-album "The Back O' The North Wind". If I compare this situation with the "flood" of Irish emigration songs I think Irish and Scottish emigration must have been something basical different. But this is a theme for historical-sociological-political-cultural study.
