Janis Joplin rules at Monterey. So, because of the animosity between SF and LA-based bands - and the fact that this festival was organized by LA-based John Phillips and Lou Adler of the Mama and Papas - Big Brother and Janis refused to be filmed at Monterey.

Here is the result. The reaction of Mama Cass Elliot, mouth agape, in the crowd says it all.
