It's just over 50 years since a young John Dankworth flew into Johannesburg to give a short series of concerts in South Africa.
Unaware, until he arrived, of the growing menace of apartheid, he joined the protest movement.
In this programme, John returns to South Africa for the first time since then, to discover how music continued to be made during the years of struggle, and how it's doing in today's rainbow nation.
He meets veterans Hugh Masekela and Jonas Gwangwa, visits a music school in Daveyton township, plus encounters younger musicians such as trumpeter Feya Faku, saxophonist McCoy Mrubata, and guitarist Louis Mhlanga.
From choir competitions to solo pianists, the programme paints a vivid picture of contemporary South African musical life and asks potent questions about the future.
