Andy, I should have recognised the Ndebele from all the Ns! I never learned any of the African languages while I was there (1964-5), regretfully. Had I done so, it would probably have been Shona, with all the Ms! I was in Marandellas (Marondera), although I travelled extensively in the holidays. Were you in Bulawayo? I seem to recall that the Matabele are of Ndebele "descent".
