Harry Belafonte’s historic week as ‘Tonight Show’ host

In the midst of the 1968 Civil Rights protests, activist and singer Harry Belafonte took over ‘The Tonight Show’ for a week, becoming the first Black person to host a late-night TV show. His guests included Martin Luther King Jr. and Bobby Kennedy, months before they were assassinated. Director Yoruba Richen and producer Joan Walsh revisit that historic week in a new documentary “The Sit-In.”
