Anyone who lived through Britain's Thatcher years won't forget them in a hurry. Politically, there were no fence-sitters: you were either with her or against her, George W. Bush-style. (Thatcher is sometimes referred to as Britain's version of Ronald Reagan, but she had little of Reagan's charm or likeability.) She was adored and reviled— and not much in between.
Under different circumstances, Thatcher might have admired those musicians for their work ethic. They practiced what she preached.
