The lost world of the Kalahari (1956) BBC TV Series?

Question

I know what you're thinking - Crikey!! How old is this questioner?
Now you've stopped laughing, who can remember the Black and White series on the TV in those early days? What I'm seeking is the haunting theme music that played at the beginning of each episode. Can't seem to find the programme
available on Video or DVD and as I don't know anybody at BBC TV archives, can anyone help me in my earnestness?

Answer 1

Try the Url , maybe.

Rain Song

The Bushmen of the Kalahari burst on the film and television world in 1957-58 with the The Hunters by John Marshall (71 minutes), which has been called the ‘classic ethnographic documentary’, and The Lost World of the Kalahari, a famous
BBC television travelogue hosted by Laurens van der Post (5 parts, 177 minutes).
The Lost World was cruder and more popular than The Hunters, concentrating on Van der Post himself and his prejudices, rather than reconstructing the lives of the Bushmen themselves as Marshall did.

Answer 2

I remember that series. It might help when you search to know that the man's name was James Herriot.
