Well, considering the Rolling Stones weren't at Woodstock, I'd say they probably didn't see too much.

Stanley Booth Levi's seat. But it was Altamont, not Woodstock. 1) Are you not talking about Altamont? The Rolling Stones did not attend Woodstock. They were not even invited. "Approximately 300,000 people attended the concert, and some anticipated that it would be a "Woodstock West." Filmmakers Albert and David Maysles shot footage of the event and incorporated it into a documentary film entitled Gimme Shelter (1970)." Source and further information: http://en.wikipedia.org/wiki/Altamont_Free_Concert "It was by invitation only & The Rolling Stones were not invited to attend. According to "Woodstock: an encyclopedia of the music and art fair" (pp145-6) the Rolling Stones weren't invited for two main reasons: One, the high performance fee they were getting was more than the Woodstock organizers wanted to pay. Two, the Stones' big hit at the time they were under consideration was "Street Fightin Man" and there was concern that their material might damage the "peace, love & understanding" nature of the concert."

If that wasn’t enough, Keith Richards’ wife, Anita Pallenberg, had just given birth to their son Marlon in London that week."

He was always telling the crowds to “Get up and shake your arses,” but now he was learning caution the hard way. The next tune was “Under My Thumb.” Mick had sung only the first line when there was a sudden movement in the crowd at stage left. A tall black man wearing a black hat, black shirt, and iridescent green suit was waving a nickel-plated revolver. The gun waved in the lights for a second, two, and then he was hit, so hard, by so many Angels, that I didn’t see the first one as he jumped. I saw him as he came down, burying a knife in the man’s back. The attack carried the victim behind a stack of speakers, and I never saw him again. His name, we later learned, was Meredith Hunter, and he was 18 years old. See the Rolling Stones and die. What Gimme Shelter, fine as it is, does not show is what happened next. We didn’t know whether Hunter had been killed, wounded, or what, but the mood seemed to change; it was as if the atmosphere had been purged. The Stones did “Under My Thumb” with no interruptions; then, at Mick Taylor’s request, “Brown Sugar,” for the first time on any stage. (They’d just written and recorded it in Muscle Shoals a few days before.) Except for a brief problem with a naked fat girl who tried to climb onstage during “Live with Me,” there were no more violent incidents. The Stones did a half dozen more songs, playing as well or better than I’d ever heard them—playing, under the circumstances, like heroes. Then we ran for our lives. Stu handed me Keith’s guitar and told me the station wagons to take us to the helicopter would be at the top of the hill, straight back and up to the left. All of us, the Stones, Jo, Ronnie, Michelle, Gram, and I, stumbled through the blackness over the dead grass and dusty clay. There was a hurricane fence at the top of the hill, but we went through a hole in it. There were no station wagons there, just a car and an ambulance. We piled into them and they took us to the helicopter. Gram and I were the last on board; the last thing you see in the film before the ’copter door closes is the seat of my Levi’s."
