This has been doing the rounds for a few months, and purports to be a recording of a telephone call made by Nancy Talbot in response to a National Geographic documentary. Nancy denies the recording is her. Is it? It does sound rather like her, to our ears, but who knows?
National Geographic documentary from 2004 featuring Andy Thomas, John Lundberg, John Wabe, Matthew Williams, Nancy Talbot, Paul Vigay, Reg Presley, Robin Allen, amongst others. Circlemakers.org make a square spiral formation for the cameras (see right).
