Question: Buffalo Springfield was a Canadian-American rock band active from 1966 to 1968 whose most prominent members were Stephen Stills, Neil Young, and Richie Furay. The band released three albums and several singles, including "For What It's Worth". The band combined elements of folk and country music with British invasion and psychedelic-rock influences, and, along with the Byrds, were part of the early development of folk-rock. With a name taken from a brand of steamroller, Buffalo Springfield formed in Los Angeles in 1966 with Stills (guitar, keyboards, vocals), Dewey Martin (drums, vocals), Bruce Palmer (electric bass), Furay (guitar, vocals), and Young (guitar, harmonica, piano, vocals).

Neil Young and Stephen Stills met in 1965, at the Fourth Dimension in Thunder Bay, Ontario. Young was there with the Squires, a Winnipeg group he had been leading since February 1963, and Stills was on tour with The Company, a spin-off from the Au Go Go Singers. When Stills' band broke up at the end of that tour, he moved to the West Coast, where he worked as a session musician and auditioned unsuccessfully for, among other bands, the Monkees. Told by record producer Barry Friedman there would be work available if he could assemble a band, Stills invited fellow Au Go Go Singers alumnus Richie Furay and former Squires bass player Ken Koblun to come join him in California. Both agreed, although Koblun chose to leave before very long and joined the group 3's a Crowd. In early 1966 in Toronto, Young met Bruce Palmer, a Canadian who was playing bass for a group called the Mynah Birds. In need of a lead guitarist, Palmer invited Young to join the group, and Young accepted. The Mynah Birds were set to record an album for Motown Records when their singer Ricky James Matthews--James Ambrose Johnson, Jr., later known as Rick James--was tracked down and arrested by the U.S. Navy for being AWOL. With their record deal canceled, Young and Palmer headed for Los Angeles, where they encountered Stills. Drummer Dewey Martin, who had played with garage rock group the Standells and country artists such as Patsy Cline and the Dillards, joined at the suggestion of the Byrds' manager, Jim Dickson. The group's name was taken from a brand of steamroller made by the Buffalo-Springfield Roller Company. The new group debuted on April 11, 1966, at The Troubadour in Hollywood. A few days later, they began a short tour of California as the opening act for the Dillards and the Byrds.

Question: Evers was born July 2, 1925, in Decatur, Mississippi, the third of the five children (including older brother Charles Evers) of Jesse (Wright) and James Evers. The family included Jesse's two children from a previous marriage. The Evers family owned a small farm and James also worked at a sawmill. Evers walked twelve miles to attend segregated schools, eventually earning his high school diploma.

The couple moved to Mound Bayou, Mississippi, a town developed by African Americans, where Evers became a salesman for T. R. M. Howard's Magnolia Mutual Life Insurance Company. Howard was also president of the Regional Council of Negro Leadership (RCNL), which began to organize actions for civil rights; Evers helped organize the RCNL's boycott of gasoline stations that denied blacks the use of the stations' restrooms. Evers and his brother Charles also attended the RCNL's annual conferences in Mound Bayou between 1952 and 1954, which drew crowds of ten thousand or more. In 1954, following the U.S. Supreme Court decision that segregated public schools were unconstitutional, Evers applied to the state-supported University of Mississippi Law School, but his application was rejected because of his race. He submitted his application as part of a test case by the NAACP. On November 24, 1954, Evers was named as the NAACP's first field secretary for Mississippi. In this position, he helped organize boycotts and set up new local chapters of the NAACP. He was involved with James Meredith's efforts to enroll in the University of Mississippi in the early 1960s. Evers also encouraged Dr. Gilbert Mason Sr. in his organizing the Biloxi wade-ins from 1959 to 1963, protests against segregation of the city's public beaches on the Mississippi Gulf Coast. Evers conducted actions to help integrate Jackson's privately owned buses and tried to integrate the public parks. He led voter registration drives, and used boycotts to integrate Leake County schools and the Mississippi State Fair. Evers's civil rights leadership, along with his investigative work, made him a target of white supremacists. Following the Brown v. Board of Education decision, local whites founded the White Citizens' Council in Mississippi, and numerous local chapters were started, to resist the integration of schools and facilities. In the weeks before Evers was killed, he encountered new levels of hostility. His public investigations into the 1955 lynching of teenager Emmett Till and his vocal support of Clyde Kennard had made him a prominent black leader. On May 28, 1963, a Molotov cocktail was thrown into the carport of his home. On June 7, 1963, Evers was nearly run down by a car after he came out of the NAACP office in Jackson.
