A recreation of the original broadcast talk made by C.S. Lewis during World War II.
This broadcast formed the basis of Chapter One of the book "Mere Christianity". You can read excerpts from the book here: http://www.amazon.com/Mere-Christianity... .This short broadcast ended up being the most read radio series' in British broadcasting history, but at the time of the live show, C.S. Lewis certainly had competition for listeners.
Britain had only two radio stations at the time. At 7:45 pm, the 'For the [Armed] Forces' frequency was broadcasting a live show by Gracie Fields, the most popular singer of the day (famous for 'Wish me luck as you wave me Goodbye'). 'The Home Service' frequency, on which Lewis was speaking, had just finished its news broadcast in Norwegian, and was about to switch into Welsh so had lost most of it English listeners. Yet by the end of the series, Lewis was so incredibly popular, the BBC immediately requested a new series and was employed by the BBC until mid 1944 - guiding Britain through some of the hardest parts of the war.
For one stretch during WW2, C.S. Lewis voice was the second most recognized voice on the BBC (after Churchill).
