Which singer led Woodstock’s opening act in 1969?

The answer is: Richie Havens. Known for his live performances, Brooklyn native Richie Havens kicked off the original Woodstock with a 50-minute set. Paul Williams accompanied on guitar and vocals, and Daniel Ben Zebulon played the congas. Some highlights were a cover of the Youngbloods’ “Get Together,” a cover of the Beatles’ “Strawberry Fields Forever,” and “Freedom” — a song inspired by the festival itself. Much of their set was improvised. It went longer than planned because other acts were delayed in traffic.Source
