Interesting comments about Susan Boyle singing songs of Scotland... I would bet she sings songs of all kinds from many sources. By the way, her family is Irish, Catholic, even though living in Scotland, and as much as other types of music, she sings hymns, as on her frequent visits to Knock. There is plenty of info now about her from interviews with her voice teacher, her neighbors, the parish priest... anyone can find the interviews with a web search.
