"I was doing a great deal of broadcasting for the various services of the BBC and they asked me to do one at the time of Stalin's death. As I rejoiced mightily in that event, since I felt Stalin to be as wicked as one man could be and to be the root evil of most of the misery and terror in, and threatened by, Russia, I condemned him in my broadcast and rejoiced for the world in his departure from the scene. I forgot the BBC susceptibilities and respectabilities. My broadcast never went on the air."
