This needs more votes. Listen to the buildup to the last verse, driven by a relentless rhythm section. Got to this one by listening to a lot of shows from August 1971 lately. They were on fire that month, as one can hear in that Hollywood and then the Berkeley shows.
Edit: Wow. This really needs more votes. People, please listen to this one and vote.
