Elvis and Martin Luther King Shared a Dream

Show the role of Martin Luther King’s activity in Elvis Presley’s art.

In his 1968 Comeback Special produced for television, Presley and his team wanted to show that the performer was not prejudiced and wanted to show his respect and admiration for the legacy of Martin Luther King. Is it shown in the musician’s works? Are there any similarities between the musical style of Black Culture and Presley’s music?
