This is the story of the Stones 1972 tour (sort of, director Robert Frank is interested in doing more than a straight documentary). Mostly its following the Stones from Hotel room to hotel room and performance to performance. Its the rich and famous interacting with the not so rich and far from famous, with everyone behaving badly. In its way its a sad story as Mick and the boys seem to drift aimlessly with in the confines of their cages. How they managed to survive it and, not go mad and continue on the road is probably a story that needs to be told. This story on the other hand is a bit dull and long at 90 minutes. It comes alive in fits and starts, mostly when we get to see one of the too few musical numbers (the Stevie Wonder/ Stones piece is amazing).
This film is rarely screened since due to a lawsuit it can only be run once a year and only when the director is present. Its rather dumb if you ask me, but the Stones were unhappy with the result and how they are seen to be. Why this film is still restricted considering all that's passed in the 40 plus years since its filming is beyond me. At this point it couldn't hurt the boys at all, since all it does is give visualization to what we knew already.
If you can manage to see this and you're a Stones fan do so. If you're not a fan you may want to give it a try, if for no other reason than its a unique and rare experience (due to the law suit that restricts its viewing).
