Woodstock revisited

A six-months pregnant Joan Baez, right, was the Friday night headliner. A 10-mile traffic jam on the main road into Bethel meant helicopters had to be chartered to airlift the acts onto the site.
Friday's opening act, Richie Havens, was forced to play for three hours before a US Army helicopter landed with the next act. "If it wasn't for the US Army, Woodstock might not have happened," Havens said.
