Pennebaker soaks up the vibe into celluloid and records the greatest show on earth. Mamas and Papas, Jefferson Airplane, Simon and Garfunkel, Hendrix all perform at their best. Though Joplin struts away with all of the awards. The beautiful people in the audience love, laugh and live in a groovy psychedelic haze. "WOW!" Yawns Cass Elliot... MAGICAL.
