Matthew Sweet hosts conversation and debate about Radio 3's 2009 Free Thinking festival of ideas, taking place at the Sage, Gateshead. Matthew is joined by a round-table of guests to reflect on the interviews, lectures and audience comment that they've heard - in particular on the festival's key theme - the 21st-century family. They assess if the complex and thought-provoking questions thrown up by the powerful speakers have elicited any answers. And how did the audience at the Sage respond?
