Carlyle was an accident brought about by my inadequate quoting skills.
But Sutherland is a total reach, officially born in the UK granted , but lived here for what? About six years? I'm sure during that time he absorbed all thinks British and this experience no doubt influenced all of his latter day choices and artistic aspirations!
Although he probably holds dual nationality, I think it's a safe bet to say he's Canadian, like Donald and raised as such in a mixed bag of US/Canadian culture.
Sorry Sutherland is disqualified! If he was Greg Rusedski however, he'd definitely be British and NOT Canadian.
