Churchill's never give-in speech

I have often retold the story of Winston Churchill visiting his old school, Harrow during the second world war.

According the story, the boys were told that Churchill, as Prime Minister of Great Britain was a very wise man and they should listen very carefully to what he would tell them. The were ushered into the school hall and sat ready to hear to words of the great man.

At the appropriate time in the assembly, Churchill was introduced to the boys. He stood up solemnly, looked at the boys and said "Never give in, never give in, never, never, never, never give in."

I was sure I first heard this story reading Martin Gilbert's work Winston S. Churchill: Finest Hour, 1939-1941.

I will have to go and re-read Gilbert's book because according to The Churchill Centre, Churchill actually gave a much longer speech.
