For years, Carawan was a leader of the Highlander Research and Education Center in Tennessee. It served as a gathering place for social-justice activists, including the Rev Martin Luther King Jr and Rosa Parks.
The song "We Shall Overcome" was adapted by Pete Seeger and others at Highlander from the spiritual "I Will Overcome."
As Highlander music director, Carawan taught the song to activists who led the sit-in movement of the 1960s. He even sang it at the first organizing meeting of the Student Nonviolent Coordinating Committee on April 15, 1960, Carawan's wife, Candie Carawan, said.
The Carawans marched with King in Selma, Alabama. Guy Carawan made recordings to preserve the civil rights movement and Appalachian folk songs.
He also helped spread another staple song of the civil rights movement. Candie Carawan said her husband was in South Carolina working with the citizenship schools that helped African Americans to pass voter registration tests when a local activist heard him sing, "Keep Your Hands on the Plow." Alice Wine told Carawan they had a different way of singing the song "Keep Your Eyes on the Prize."
