The Metropolitan Library System will host two events honoring American Folk singer and social activist Pete Seeger’s 100th birthday. Robert Williams of the Woody Guthrie Folk Festival and the musical duo The Rix will perform a musical and spoken word show titled Pete Seeger & Saving the Hudson River: The History of Environmental Activism in Music. Proceeds from their tour benefit the cleanup of the Hudson River. The first performance will be July 12 at Southern Oaks Library at 2 p.m. and the second performance will be July 14 at the Bethany Library at 4 p.m. “We are excited to host an event honoring the great musician and activist Pete Seeger,” Adult Services Manager for the Metropolitan Library System Kellie Delaney said. “Seeger made his mark on American folk music history and even worked with Oklahoma’s own Woody Guthrie.” Seeger was best known for songs Where Have All the Flowers Gone, If I had a Hammer, Turn! Turn! Turn! and My Oklahoma Home Blowed Away. He was considered an activist for his belief that music could make a difference and his songs were created with political and environmental implications in mind. He worked with other impactful musicians of the Depression era including Leadbelly and Woody Guthrie.
