Query: Essential Lennon

This DVD is essential for any serious Lennon fan. Too many reviewers worry about the avant-garde nature of the Yoko Ono performance. The film documents one of the best and most feral rock concerts ever given. Lennon's performance is raw and exciting. And, if you've ever doubted Lennon's estimation of "Don't Worry Kyoko..." as one of the best rock songs ever, you must see him and Clapton getting into a fine guitar groove that works like a mantra. And the live version of "Yer Blues" is as exciting as the performance in the Stones' "Rock and Roll Circus" (not to mention "Cold Turkey"! This is a classic moment in rock history that testifies to the power of Lennon and the Plastic Ono Band. Don't miss it! I waited years to get this DVD. It rocks.
