From an article in today's New York Times about Shane McGowan, currently on The Pogues' US St Patrick's Day tour --
When, during one tangent, the term "British Isles" arose, Mr. Cashman [Shane's assistant] was quick to correct it. "Don’t use the phrase British Isles," he said. "It’s England, Scotland, Wales and Ireland." He added, "If you say it any other way, he’d probably throw his glass at you."
Another usage that avoids rows is the label for this post.
