"Dean cadalan samhach, a chuilean mo ruin." is half and half. Part sorrow about leaving Kintail and coming to America during the winter, Yet it also sings of hope for the spring in the new world. But as far as I'm aware there are few (if not any)overtly happy songs of this type in the Scots Gael plethora. There is "A Dance called America" a Runrig song which talks about the Gaels making a livly dance to accumpany the euphoria surounding the tales of America they were fed by officialdom.
