I made some good friends in Johannesburg, but the colour problem depressed me.  Africans were not allowed into the City Hall concerts, and when I went back there in 1962 I asked to play to them in their own habitat, a ramshackle place with a small upright piano, introducing the programme informally, including the Italian Concerto, the Kinderszenen, and Bartók’s Bulgarian Dances.  At the end they sang me some part-songs and madrigals excellently and with love, one of the most touching thank-yous I ever received.
