The same year, "People Got to Be Free", a horn-punctuated plea for racial tolerance (the band was known for refusing to tour on segregated bills) just months after the assassination of Martin Luther King Jr. and of Robert F. Kennedy, became their third and final U.S. #1 single, and their sixth and final Canadian #1. It was also their final U.S. Top Ten hit, although they remained a Canadian top 10 act for the next few years.
