Longtime musicians and activists David Crosby and Graham Nash performed a concert downtown Tuesday at the Occupy Wall Street protest site.
The duo played an acoustic set of protest songs.
"It just all goes back to, like, the '60s when groups got behind movements like this," said Phil Connolly, who watched the show.

Crosby, a Rock and Roll Hall of Famer of Crosby Stills and Nash fame, visited the park last week.
Crosby and Nash are the latest musical act to stop by the protest headquarters.
Others have included Kanye West, Talib Kweli and Jeff Mangum.
