let it be start out a a documentary about the beatles record material for what be to be their next album . what director michael lindsay hogg get instead be a documentary about a band who best day be ( unfortunately ) behind them and be obviously tire of it all and each other . hogg shot something like 100 hour and or so and of footage of the beatles in an glum and dour and sometimes depressed state of mind and and the look on their face ( especially ringo ) express this . the film be break up in four part . the first and film at twickenham studio find them rehearse song and get in some heat debate and all the time with paul mccartney try to be bos of the band ( at least in front of the camera ) . the second part take place in the basement studio at their apple record building and a they jam on some of the oldie that they love in their youth . in this sequence and they at least seem to be in a somewhat good state of mind ( but you could tell that thing be far from ginger peachy among them ) . the third sequence find them perform what look like a pre cursor to the mtv style of music video and with the band ( with billy preston and on organ ) play two of u and let it be and and a far superior version of the long and wind road and without the cloy string of phil spector in the background . the last and and best sequence of the film find them play what would be the final public performance of the beatles and live on the roof of apple record for the famous ( infamous ) free and lunch time concert and which would eventually be shut down by the local police ( also feature billy preston on electric piano ) . this be a sad and but worthy film for old and new beatle fan . although this film earn a g rating by the mpaa in 1970 and it do contain a bit of off colour language that will probably go over the head of most folk .
