"One thought, the ending was from Tony’s point of view as he is whacked. Everything just ends instantly, right when you least expect it."

(Damn!) already deleted it, but in retrospect I think you got it.

Flashback shirt, antique diner and music, everybody happy (Willow no longer the self control freak & AJ acting almost human)....

Tony gets his notice and goes out remembering the good times.

Working hard to get my fill,
Everybody wants a thrill
Payin anything to roll the dice,
Just one more time
Some will win, some will lose
Some were born to sing the blues
Oh, the movie never ends
It goes on and on and on and on

"Tony...goes out remembering the good times."

I should add that my opinion all along has been that Tony is a fairly decent guy trapped (literally) in a really, really, lousy job.
