Following the lead of fellow political songwriters like Pete Seeger, Arlo Guthrie and Tom Morello, David Crosby and Graham Nash will play for Occupy Wall Street protesters tomorrow. Nash and Crosby will play Occupy Wall Street’s New York home base in Zuccotti Park at roughly 3 PM. Crosby and Nash—who have toured and recorded as a duo as of late—are in New York for a performance with Crosby, Stills & Nash tonight.
