Finished watching it last night, absolutely superb.
Peter Jackson made a superb documentary out of the footage. It was just amazing to watch songs like Get Back and the Long And Winding Road bring created.
I thought you could see the cracks starting to appear though. Harrison clearly isn't happy with the musical direction. He seemed a bit fractious at times and probably needed to go and do his thing. He's clearly really into Eastern Ideas and wants more input into songs. If he'd not been in The Beatles, he'd have had a fine career anyway. Lennon is distracted by Yoko and McCartney is on the road to becoming a family man. Ringo seems to just hold it all together.
You could see the spark at times with Lennon and McCartney. It was brilliant to watch and amazing to see it. I thought McCartney came across very well - for someone who's not been trained, his ear for music and melody is the equal of any musician, in any era.
As an aside, not many class Let It Be as a great album - I've never heard anyone say it's a great album. They were that good that even an album with Two Of Us, Dig A Pony, Across The Universe, Let It Be, The Long And Winding Road and Get Back isn't regarded as some of their best work. Any other band who made that album would be lauded for it. It's also astonishing they wrote many of these songs around the same time as Abbey Rd.
The gig on the roof was just superb wasn't it - a brilliant idea and great to see how it panned out on the day.
