David Crosby and Graham Nash are the latest stars to show their support for the Occupy Wall Street movement.

Nash tells "Rolling Stone" that the protest is evidence people are "waking up," which he says is "what we do as musicians."  He explains that as a performer it's his job to "wake people up," and adds that he thinks it's important for people to be aware.  Nash says he doesn't want to "talk to sheep," but "wants people that are alive and thinking and trying to do something positively to change their situation."  Crosby is a little more direct in adding his assessment of the demonstration, saying "everybody is realizing that they're getting screwed."  Crosby and Nash visited the crowd at lower Manhattan's Zuccotti Park Tuesday afternoon.  The duo played a five-song acoustic set that included their classic hits "Long Time Gone" and "Teach Your Children."
