Janis Lavine, then a 17-year-old, is featured in the 1970 documentary in her pink paisley, puff-sleeved dress, leaning up against a Harley Davidson. She had lugged her friend Deb's belongings, hoping to find her at the concert.
Debby eluded her for three days, but she found a spot up front to hear her "rock hero," Jimi Hendrix.
"I looked at the muddy field behind me filled with shoes, sleeping bags, blankets in disbelief that most of the concert-goers had left," she told ABCNews.com.
"As he played, he handed a guy in the press pit his Benson & Hedges cigarette, who turned around and gave it to me. As I puffed and passed the cigarette on, I reached Nirvana!"
"I was a teen lost in the moment and had no idea that this would become history," said the now 57-year-old from Beverly, Mass.
"As I trudged up the hill I lost one of my sandals in the sea of mud. Alone and still stunned I made it back to New York City with one shoe and Deb's and my stuff."
Larry Gross, who at 57 has devoted his life's work the nonprofit Coalition for Economic Survival since attending Woodstock as a 17-year-old had his own Age of Aquarius moment.
A bit "hung over" sitting back at their car on the third day, Gross and his friends waited for the grand finale performance of Jimi Henrdix.
"All of a sudden a car comes up the main road and stops right next to us," he told ABCNews.com. "He sticks his head out the window and looks right at me and raises he fist and says, 'Pilgrims together, on forever.'
"We sat there for a second silent," said Gross. "Then we looked at each other and said who was that? Yes, it was Hendrix all in his pearly outfit, right there."
