Alan Whicker has been making television programmes from all over the world for decades. Sandi Toksvig asks him about the appeal of travelling and whether it ever wears off. He tells her about revisiting some of the people and places that featured in his earlier reports, and reflects on the way the world has changed in the intervening years. Stephen Fry is not a man who likes to rough it, but he is forced to do just that in visiting the remoter parts of the world to see some of the most endangered species. Sandi asks him whether seeing the aye-aye, the blue whale and the komodo dragon was really worthwhile - especially as it involved not just discomfort but seriously fracturing his arm.
