Jane Goodall speaking from a lectern, wearing a green top and her grey hair in a ponytail: "My wonderful welcome comes to you from the forests and hills of Gombe National Park in Tanzania: the sound that you would hear if you came – some of you have been – but if you go to Gombe and climb the hills in the morning, the sound of a chimpanzee greeting the day, announcing, 'Here I am. Who's out there?'" She does a dramatic rendition of a chimp's pant-hooting: a series of audible intakes of breath that develop into hoots that get louder and louder then stop. "Hello!" The audience laugh appreciatively, then applaud.
