Tune in to BBC Radio 4's "Excess Baggage" (available worldwide online), on Saturday September 12th at 10a.m. to hear Stephen Fry discussing the making of the Last Chance To See TV series. The show will also be available to listen again after broadcast. It is also available as a free Podcast through RSS, iTunes and other services. This week's show also includes an interview with the legendary travel broadcaster Alan Whicker.

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.

And if you're quick, David Attenborough's "A Point of View" last week featured the story of the Dodo and other flightless birds.
