This priceless letter comes from the April 1972 issue of Records & Recording magazine, and perfectly encapsulates what was a very popular viewpoint at the time. I wonder what became of Mr. Sealey, with his 'inviolable criteria', 'alarm' and 'despair'; I imagine he found the steady assimilation of pop into the cultural mainstream increasingly hard to bear.
