"over 100 UK Olympic competitors will not relate to "God Save the Queen"."

Absolutely. Over 100 would not relate to it for that particular reason. There could well be other reasons too. Let's be honest had an english player not sung the anthem then no one would have bothered or even mentioned it. It is the usual Scot baiting. When world cups are on some members of the media obsess over whether Scots will be supporting England or not. Now we're in the same team it is whether we sing the anthem or not :-)
