Murder! - the alternative ending

The following DVD releases of Murder! contain an extra "alternative ending" which is, in fact, the last 10 minutes of the US version of the film:

The US version inserts two segments which appear to be designed to help explain the ending to the audience.

In the screen grabs shown below, grabs with a green border appear in the main UK version of the film and those with a blue border are from the inserted US segments.

In the first segment the cast are shown returning to the dressing room, along with the dead Fane being carried in on a stretcher (covered by a blanket). Sir John is handed a note from Fane which is addressed to him. He glances at the note and then walks out of the room.

The dialogue from this section is:

Sir John: [walking through the crowded room] Excuse me.
Manager to Sir John: [referring to Fane] Neck broken.
[the Manager hands Sir John a letter]
Manager: This is for you, Sir John. I don't know whether it's anything to do with this.
[Sir John opens the letter]
Sir John: [to Markham] All right, Markham.
[Sir John contemplates the content of the letter]
Sir John: Is the manager there? [to the Manager] You know where to find me?
Manager: Yes, Sir John.
Sir John: I shall be able to throw some light on this. [to Markham] All right, come along.
[they exit the dressing room]

In the second short segment, Diana Baring is shown leaving prison and meeting Sir John. This is followed by a scene of them together in a carriage -- Sir John says to her "Now, my dear, you must save those tears... they'll be very very useful... in my new play".
