What Influenced Sir Winston Churchill’s Rhetorical Style?

I was interviewed as part of the BBC Radio 4 documentary, “Churchill’s Secret Cabinet” (which originally aired on July 6th).  My commentary on the music of Sir Winston Churchill’s rhetoric begins at the 48:11 mark.

Here is an excerpt from the program description:

Clement Attlee once claimed that Churchill led Britain to victory in the Second World War through his words. But what influenced these words and their delivery?

The answer lies in a newly discovered wooden cabinet containing not only Churchill’s private collection of gramophone records, but also rare recordings of his unknown speeches.
