Listen to the entire lost Dr. Martin Luther King Jr. speech from 1964: https://owl.li/HysSz (Democracy Now! and Pacifica Radio Archives exclusive broadcast.) 

On December 7, 1964, days before he received the Nobel Peace Prize in Oslo, King gave a major address in London on segregation, the fight for civil rights and his support for Nelson Mandela and the anti-apartheid struggle in South Africa. The speech was recorded by Saul Bernstein, who was working as the European correspondent for Pacifica Radio. Bernstein's recording was recently discovered by Brian DeShazor, director of the Pacifica Radio Archives. Today is the federal holiday that honors King.
