1. Beatniks, hippies, flower children and rock legends gathered together not in Woodstock, but in the little town of Bethel, rural New York State.
2. The idea for the festival came from band manager Michael Lang and Artie Kornfeld, a songwriter turned record company executive. They wanted to raise money to build a recording studio in Woodstock, upstate New York, a haven for artists including Bob Dylan, The Band and Van Morrison.
3. There was no suitable site in Woodstock, so organisers opted for Wallkill, 40 miles away. But residents blocked their plans, so dairy farmer Max Yasgur stepped in to offer his alfalfa field, in the neighbouring hamlet of Bethel. A deal was struck for $75,000.
