He turned out to be the Minister of Finance.

I finally arrived in Lagos only just in time, for Dot and Antony were preparing to depart. Their time in Nigeria had been one long love affair: they had adored the Nigerians and been adored in return. Every evening there was a farewell party, one or two at the High Commission, the rest in various Nigerian houses. The most memorable of all was given by the Mayor of Lagos. He had a resident orchestra of about twenty, all women and all on various kinds of percussion, belting out rhythms such as I have never heard before or since—rhythms of such extraordinary subtlety as to defy any system of musical notation. They played in a huge garden, in the middle of which I suddenly spotted a gigantic man in a magnificent silver robe adorned with dollar signs, dancing all by himself, an expression of sheer ecstasy on his face. I watched him, fascinated, and eventually asked who he was. He turned out to be the Minister of Finance.
