IMHO:
Per the above posts, at the bottom is the scene in question which IMHO proves that that at the very least, this scene definitely is now placed in the correct place and at the post, is strong supporting evidence of how the non-linear Theatrical version of Godfather Part II came about.
Astonishingly, I had a download on an external drive from years ago of the The Epic in HD. I also have the The Epic on VHS, and it is NOT the same. This download version seems to e a hybrid of the the Novel for TV that was screened in the UK (in SD) and The Epic. The run time matches The Epic but the on screen titles are a "A Novel for Television: The Godfather Epic Saga 1901-1959". So ...Parts 1 & 2 only. Now, this is very odd. The Novel for TV, including AMC's reworking does not have the secondary title. I've checked my off air recording of the Novel for TV, and it does not Either. Saga is Saga, which is Epic cut down, so we can ignore that VHS atrocity. But this IS the Epic, and in HD....There are no on screen identifiers, nothing that indicates it is a fanedit, and I can recall where in hell i got this from, but I have it. Result! And now that scene has been added BACK into the edit with the full audio.
I am annoyed that I did not realize that I do have the audio elsewhere in SD, and I could have re-done the scene to include it, but now I do not have. PLUS, it has given me a better transition too. How so, read on.
As I said previously, this transition from Michael saying goodnight, to entering the room with Kay was VERY hard to pull off. Once I finally decided to use the audio from AMC, which transitions to Young Vito that music, I had to time the music to end as Michael picks up the drawing. To that, I had to rebuild all the ambient audio. NOw, I have a different music cue, which is about 15 secs shorter. That is good, coz the musical transition now is not back to back. That aspect of my version bothered me EVEN when I polished it. This music cue ends earlier and is also tonally perfect...as it should be coz the filmakers put it there when they made The Epic....However, there is no ambient audio underlying that music cue. But the materail also has Michael leaving Anthony's room, which is not in any other version. This actually works PERFECTLY coz I already rebuilt the ambient audio for my fix. Further, I had to slow down the music cue I used, and it was not an ideal solution frankly.
So....here are the two versions of the scene, unaltered.
Enjoy
