Cartoonist Gerald Scarfe introduces a chopped up, looped up love letter to sound, singing, seduction and the power of the voice. So take a moment to consider the air in your lungs while listening to Bobby McFerrin and Beardyman make amazing musical sounds. Here you'll hear why our vocal chords work much like a duck, and why Theresa May represents a century long pattern of working women who have lowered their voice. Elsewhere Stephen Pinker mingles with Stephen Fry; Donald Trump reveals the power of saying the right thing to an audience who want to be seduced; and John Prescott tangles with Noam Chomsky over grammar and class. The producer in Bristol is Miles Warde.
