Eddy Grant’s career (with the Equals and as a solo artist) was evidence that commercial success did not preclude political content. ‘Jo’anna’ is Johannesburg, and Grant’s protest is at the apartheid state, which ‘keeps a brother in subjection’ and which is buoyed up other states and by its gold mines. The song’s darker sentiments are themselves leavened by a chorus that was to give Grant a No.7 hit – and a ban in South Africa.
