Richard has been gigging back home in Cheddar and meets a face from his past. His guest this week is broadcaster, author, President of Humanists UK and part-time Victoria Coren lookalike, Professor Alice Roberts. The pair discuss meeting the Blue Peter team, the behind the scenes debauchery of Time Team and what happened if they didn’t find anything, the great human journey and how much monkey business ended up affecting our DNA, an island of dead hobbits, Australian hypocrisy, how we might improve our useless human bodies, what God was thinking and the Sliding Doors world where dogs never existed.
