There's a brief excerpt from Pride that's labelled as "Boston '87". Since the documentary was filmed at the end of May (around the Modena shows), it would be strange that it features footage from the September Boston shows - so I assume it's wrongly labelled footage from the Worcester shows. Worcester is around 75 kms away from Boston so I can understand the mistake, but my point is: they were already filming the Joshua shows in video (and with a very similar format to R&H) way before the third leg? That means there's a lot of lost proshot footage from the 1st and 2nd leg, sitting in someone's vault

So they were filming some (or all) shows prior to developing the idea of doing Rattle And Hum. God knows how much that footage might be worth to fans nowadays... 
I'll take it!
That's an incredible story. One day I'll ask you more about this. Wow.
