David Crosby, Graham Nash to Perform at Occupy Wall Street (Video)

Two-thirds of Crosby, Stills and Nash take to Liberty Plaza at 3 p.m. ET

Musicians David Crosby and Graham Nash – two-thirds of the famous trio Crosby, Stills and Nash – will perform at Occupy Wall Street’s headquarters in Zuccotti Park on Tuesday.

The protest movement’s website says that the two folk legends will perform “an acoustic set of protest songs” at 3 p.m. ET.

Both Crosby and Nash, as well as associated acts like Neil Young, are well-known for their political activism spanning back to the late 1960s and the anti-war movement.

Occupy Wall Street participants have been at the receiving end of hippie comparisons, but that is a label they are not entirely thrilled with.

In performing at Liberty Plaza, Crosby and Nash become the most famous musicians to play at one of the protests. Then again, that may depend on what generation you belong to.

Rage Against the Machine’s Tom Morello has performed at demonstrations across the country, including in both New York and Los Angeles, under his solo moniker – The Nightwatchman. 

Morello won an MTV "O Music Award" for his performance at Zuccotti Park.

For those unfamiliar with Crosby and Nash's music, or those who haven't heard it in some time, here's a video of Crosby, Stills and Nash performing "Long Time Gone" at the Glastonbury music festival in 2009:
