The fourth set of talks did not take place until 1944. The script drafts had a much wider scope originally, and Lewis prepared for 10-minute talks when the BBC was giving him 15. The timing of these talks was important and strictly adhered to because due to technology and WWII, Germany would broadcast propaganda through the English-spoken "Lord Hawhaw" during any dead air. Due to the timing of the fourth set of talks (10:20 pm), Lewis said he couldn't do them all live and would have to record some.
