In his hearty tenor, Mr. Seeger, a beanpole of a man who most often played 12-string guitar or five-string banjo, sang topical songs and children’s songs, humorous tunes and earnest anthems, always encouraging listeners to join in. His agenda paralleled the concerns of the American left: He sang for the labor movement in the 1940s and 1950s, for civil rights marches and anti-Vietnam War rallies in the 1960s, and for environmental and antiwar causes in the 1970s and beyond. “We Shall Overcome,” which Mr. Seeger adapted from old spirituals, became a civil rights anthem.
As much as the banjo, Seeger's instrument was the audience.
Honing a skill he learned at labor rallies during the 1940s, he was a virtuoso of sing-alongs. He was still at it at the age of 90, as shown here with Bruce Springsteen during President Obama's 2009 inauguration at the Lincoln Memorial:
From the New York Times obit:
Mr. Seeger was a mentor to younger folk and topical singers in the ‘50s and ‘60s, among them Bob Dylan, Don McLean and Bernice Johnson Reagon, who founded Sweet Honey in the Rock. Decades later, Bruce Springsteen drew the songs on his 2006 album, “We Shall Overcome: The Seeger Sessions,” from Mr. Seeger’s repertoire of traditional music about a turbulent American experience, and in 2009 he performed Woody Guthrie’s “This Land Is Your Land” with Mr. Seeger at the Obama inaugural. At a Madison Square Garden concert celebrating Mr. Seeger’s 90th birthday, Mr. Springsteen introduced him as “a living archive of America’s music and conscience, a testament of the power of song and culture to nudge history along.”
During the McCarthy era Mr. Seeger’s political affiliations, including membership in the Communist Party in the 1940s, led to his being blacklisted and later indicted for contempt of Congress. The pressure broke up the Weavers, and Mr. Seeger disappeared from commercial television until the late 1960s. But he never stopped recording, performing and listening to songs from ordinary people. Through the decades, his songs have become part of America’s folklore.
“My job,” he said in 2009, “is to show folks there’s a lot of good music in this world, and if used right it may help to save the planet.”
Even as he aged and many of his causes lost ground, Seeger never gave up hope. The obit concludes:
Mr. Seeger kept performing into the 21st century, despite a flagging voice; audiences happily sang along more loudly. He celebrated his 90th birthday, on May 3, 2009, at a Madison Square Garden concert — a benefit for Hudson River Sloop Clearwater — with Mr. Springsteen, Dave Matthews, John Mellencamp, Joan Baez, Ani DiFranco, Roger McGuinn of the Byrds, Emmylou Harris and dozens of other musicians paying tribute. That August he was back in Newport for the 50th anniversary of the Newport Folk Festival.
Mr. Seeger’s wife, Toshi, died in 2013, days before the couple’s 70th anniversary. Survivors include his son, Daniel; his daughters, Mika and Tinya; two half-sisters, Peggy, also a folk singer, and Barbara; eight grandchildren, including Mr. Jackson and the musician Tao Rodriguez-Seeger, who performed with him at the Obama inaugural; and four great-grandchildren. His half-brother Mike Seeger, a folklorist and performer who founded the New Lost City Ramblers, died in 2009.
Through the years, Mr. Seeger remained determinedly optimistic. “The key to the future of the world,” he said in 1994, “is finding the optimistic stories and letting them be known.”
