Woodstock

Fifty years later, the site of the Woodstock Music and Art Fair is on the National Register of Historic Places. For some who were there, it's a place of pilgrimage and memories.

In the pre-digital age, shooting video was unwieldy and expensive. But in the late 1960s, storytellers calling themselves "Videofreex" used the first portable video recorders to film a changing world.

His fiery performance at Woodstock is legendary. The band would go on to have a hit with "I'd Love to Change the World."
