The name of the singer is Gilberto Gil. He is the current Minister of Culture. At one time, during the dictatorship, he was in exile, I believe, in London. He is currently well-known for his samba-reggae music style, an adpatation of reggae that took root in Brazil when Bob Marley visited, just before his death.
