The Sundance Film Festival kicks off in Park City, Utah Thursday.

This year, one of the highlights is the documentary film about the making of “We Are the World,” the American musical effort to raise money for famine relief in Africa.

It followed Bob Geldof’s “Do The Know it’s Christmas?,” and Canada’s “Tears are Not Enough,” which backed the same cause.

The film is called “The Greatest Night in Pop” and features never-before-seen footage featuring most of the major names in American popular music of the time.
