Bernard LaFayette Jr. gathers some singers.

Singing is part of the nonviolence movement. Here is Dr. Bernard LaFayette Jr. singing with the participants of the International Nonviolence Summer Institute for trainers(Level I) and organizers(Level II). Singing in the Civil Rights Movement created unity, eased fears, appeared to show confidence, this created a unified group to attack not just an individual person, a form of political message through song, picketing and marches were set to the song. Everyone sings, no exceptions.
"Music was absolutely vital and central to The Movement." quoting David Hadley Finke
