He dropped Coltrane on Moscow
Willis Conover, the Voice of America disc jockey who fought the Cold War with cool music, captured the hearts and liberated the spirits of millions of listeners behind the Iron Curtain beginning in 1955 when his show first when on the air.
"Conover would bombard Budapest with Billy Taylor, strafe Poland with Oscar Peterson and drop John Coltrane on Moscow." So reports his obituary.
He was unknown in the U.S. because by law the radio shows of the Voice of American were not permitted to be broadcast in or to this country.
