William Roscoe Mercer (1927-2000), better known as Rosko, was a famous disc jockey. In the rare sound recording below, from 28 December 1962, you hear him announce the Ray Charles "In Person" concert ('with The Raelettes and his orchestra) at the Civic Auditorium that night. Rosko jokingly calls Ray the Secretary of State*, probably referring to Charles' many tours abroad.
* Not to be confused with Dizzy Gillespie who put himself forward as a presidential candidate in 1964. If he were elected, the White House would be renamed The Blues House, and a cabinet composed of Duke Ellington (Secretary of State); Miles Davis (Director of the CIA); Max Roach (Secretary of Defense); Charles Mingus (Secretary of Peace); Ray Charles (Librarian of Congress); Louis Armstrong (Secretary of Agriculture); Mary Lou Williams (Ambassador to the Vatican); Thelonious Monk (Travelling Ambassador), and Malcolm X (Attorney General). His running mate would be Phyllis Diller.
