Another rock opera to write, darn it

Wouldn't it be interesting to make a film of how the Rolling Stones' Exile on Main St. came to be? Plenty is known about it -- but what would it be like to be there? Everyone wants to look at bands' whole arc, yet how interesting to zoom in on that moment that seemed to encapsulate all the roots and decadence and greatness that would come to define the band. (Plus they had Nicky Hopkins back then, always a good thing, IMHO.)
