I do indeed sing an Anglicised version, which Anne Alderson scribbled down on a beermat at the legendary Collingwood folk club, Thornaby on Tees, during the 1980s. I never bothered doing a collation job on it, and have sung exactly these words ever since. I agree with Jim McLean that the McDonald verse is not traditional, but who added it I don't know. I've always been reticent about singing it in Scotland!
