This fund drive edition, "The Power of Song," is devoted to a two-hour celebration of Pete Seeger's 90th birthday (May 3), featuring new and old Seeger recordings, and the just-reissued 5-CD box of "American Favorite Ballads," plus an Australian reissue of three very political late '60s-early '70s albums. Music can change people and the world, as Seeger has so often demonstrated over the past seven decades.
