That was the great classical music DJ, Bill Watson, who along with Jean Shepherd, made radio works of genius in New York city for so many years. The classical station he worked for belonged to one William F. Buckley, who ultimately did the conservative/capitalist thing and sold his radio station to an outfit that intended to make it yet another rock outlet, thus putting Watson, who shared Buckley's values and philosophy, out of a job. He worked briefly at WQXR, the one remaining classical station in New York, but couldn't adjust to the playlists and potted-palm formality there. At last he was taken in by non-commercial free-speech left-wing WBAI, which is where he did that reading of Alan Mendelsohn the Boy from Mars.
