Video: Crosby, Nash at Occupy Wall Street

Living folk-rock legends David Crosby and Graham Nash have joined a growing group of famous musicians to offer support of the nationwide Occupy Wall Street movement by stopping by the protest for a performance. Last month, we shared a clip of Jeff Mangum serenading the crowd and unleashing a few rousing sing-alongs at the scene in New York City, and now comes footage of two CSNY greats rekindling a few classics for the cause. In addition to an unplugged take on Woodstock favorite “Long Time Gone,” the pair performed “Military Madness,” “What Are Their Names,” “They Want It All,” and “Teach Your Children” on Tuesday.

Check out a clip of Crosby and Nash leading the crowd through the latter cut — a tune that remains brilliantly relevant after all these years — below:
