It looks like the rare unreleased “The Beatles - Let it Be (1992 film restoration)” is on Dailymotion.
For those not aware: this version of the movie is a direct transfer from the restoration done by Ron Furmanek in 1992, making this one the best image (new transfer from original negatives) and audio (mono on Twickenham section, glorious stereo afterwards)
It appears that the DVD of this from Rutracker has far better picture quality than the Dailymotion and the one from Dailymotion is severely cropped.
