If I've convinced you, then I'm starting to doubt myself.
I'm messing with you but concessions (is that the right word?) here in France have had a limited time for decades if not centuries, as far as I know (I'm not very aware of that topic).
Please do!
However, with Leone, of course, it's never just about story. It's about the artwork. The filming, the music, the construction, the production design, etc. etc. Therefore, even if that scene is unnecessary to explain the plot, that doesn't mean the movie wouldn't be better without it... And who knows, maybe one day, if we really get ALL the deleted scenes, we'll know for sure
