The “stars” included Sammy Davis Jr., Peter, Paul and Mary, Tony Bennett, Pete Seeger, Joan Baez, Mahalia Jackson, Sidney Portier, Nipsy Russell, Mike Nichols, Elaine May, Alan King, Tony Perkins, Shelly Winters, Odetta, Nina Simone, and Leonard Bernstein.

A rally was held to inspire the marchers and prepare them for the next day’s journey to the Alabama State Capitol. Dr. King was cheered when he appeared on stage and said “This is the greatest march on any capitol that there has ever been in the South. This will go down in history as one of the greatest developments in the civil rights movement.” The next day, King delivered one of his most famous speeches, “How Long, Not Long”.
