Crosby, Stills, Nash & Young
Folk rock supergroup Crosby, Stills, Nash & Young began their 16-song set around 3:00 a.m. Made up of former members of The Byrds, The Hollies, and Buffalo Springfield, Woodstock was only their second gig. Their nine-song acoustic set included "Suite: Judy Blue Eyes" and "Marrakesh Express." The electric set that followed included "Long Time Gone" and "Find the Cost of Freedom."
They later recorded the song "Woodstock" to commemorate the festival, and for a while they rivaled The Beatles in terms of popularity. But their superegos caused the group to disband in mid-1970. They've all enjoyed success as solo artists and have reunited in various configurations to record and tour over the years.
