I was looking up some quotes and found this GF2 Script link...

In it, there is a scene where Frankie Pentangeli has a meeting with The Rosato Brothers in a restaurant with a lot of dialogue.

It appears in this script right before Frankie returns home to find Michael waiting for him at the old Corleone house.

This is not the scene where Frankie is strangled at the bar meeting - it is a completely different scene.

Was the scene with Frankie & Carmine Rosato actually shot? Obviously, it was never in the final movie.
