Ray Charles Interviewed For Martin Luther King Tribute Show (1977)

The Sun Reporter of 13 January 1977 announced that the following day Channel 9 in San Francisco was to broadcast I Have a Dream: Martin Luther King Jr., 1929-1968.
The ‘show’ seems to have had an odd format: “an hour-long television tribute to the memory of the civil rights leader”, including “interviews with Ray Charles, a poetry reading by Maya Angelou, gospel music from the Duffey Singers, and a dance performance choreographed by Raymond Sawyer. Maya Angelou will portray the role of grandmother”.
