This is what the huge gathering at Woodstock looked like to the artists who were lucky enough to go out and take the stage. It's a swarming mass of humanity that extends out from the front row to the very edges of the horizon. To the performers, it must have been almost overwhelming.
Estimates place the attendance at Woodstock as being in the region of 400,000. That's well on its way to having half a million people in the same place at the same time; more than a lot of towns and even some cities. To give a sense of perspective, even the world-famous Glastonbury Festival in England can only admit around 130,000. The normally small and quiet town of Bethel, New York, must have wondered what hit it. This was more than just a festival. It was a movement!
