Got news for ya, 98% is about as done as any sequence gets ...at least around here
The tweaks are endless but at some point one has to simply declare that its good enough / the audience won't notice. But if its something that really is getting your goat, well then you might have to tweak it some more, and some more, and some more still...
Trust me when I tell you, seeing all the little kids dancing in the street and singing along with the show makes all the effort so worth it!
