Yes I remember the occasion. It was filmed in 1961 and released in 1962. I have both a VHS and DVD copy of Hatari.
My Mum worked as the assistant to Ben Benbow at the Safari House Hotel where the company stayed, so got to know a lot of the actors and crew. I have autographs from all the actors- Hardy Kruger, Elsa Martinelli, plus some others I cannot recall now. I have two autographed 8x10 pictures of my mum and John Wayne. I can still see all the Zebra painted Jeeps parked in the hotel carpark. I remember the visit to the school and being on the playing fields at the back of Junior School but no details.
My time at the school was great.
