They got away with it long enough to win a Grammy and somehow even kept it going after the real singer, Charles Shaw, told reporters the truth. To solve that, Farian gave Shaw $150,000 in hush money, and suddenly he had no idea what those reporters were talking about. In 1990, that was totally an option. In this age of recorded everything, you'd have to be a conservative politician to try something that retarded."''
