On May 9, 1970,  there was a March for Peace from Hamline University to the State Capitol, organized by Barry Knight.  The Paisleys were playing at the finish line, and there were speeches by Indian activists Clyde Bellecourt and Dennis Banks.  That night there was a concert at Macalester College with the Flying Burrito Brothers.
