Hey, Lonewolf - I have that "3 days of peace and music" poster framed and up on my bedroom wall - I bought it at Woodstock.
I was interviewed a couple of days ago by the local newspaper because I was the only one they could find around here (Victoria BC) who had actually been there!
As I said in the interview, in my mind the stars were Janis Joplin and The Who (the Harlots of 42nd Street should have been there), but the real unknown star of the show was Ravi Shankar. The crowd reaction to his 45 minute piece was instantaneous and intense beyond that for any other act, yet I seldom see his presence even mentioned.
