I want to thank my brother Barry, for sharing this incredible find! You can actually listen to about a 15 minutes of C.S. Lewis talking in his real actual voice.

Beyond Personality: The New Men: 1944
An introduction to The Great Divorce: 1948

These audio clips were originally recorded as BBC broadcasts, and are now archived in RealPlayer format on the BBC website located here.

My first impressions are that he sounds way more like an Englishman than I imagined!

This is totally, really, way cool!
