Roger Bolton hears a range of listener views on the Today programme's 60th anniversary live edition. Did some of the presenters bray over gags about sexual harassment and assault?

To kick off the new series of The Moral Maze, Radio 4 has been working in partnership with Dundee University to trial a new piece of technology that aims to help the listener become a more effective debater. Roger gives this innovation a try.

Roger also goes behind the scenes at the Ken Bruce show to find out more about how he and his sidekick Lynn Bowles interact with their listeners. and speaks to the first - and now former - Radio 4 Poet in Residence Daljit Nagra to find out more about the role.

And, erm, well, so... The verbal tics that drive you mad. Why do they pepper so much of a BBC radio broadcaster's natural speech? Socio-linguist Heike Pichler explains what's really going on.

Producer: Kate Dixon\\nA Whistledown production for BBC Radio 4.
