Sometimes this recording circulates with a reprise of the second half of "Who's That Woman?" edited in after the song finishes. This addition seems to have been intended to simulate the way the show was performed at the first Broadway preview (March 24, 1971), when it was performed with an intermission that came after "Who's That Woman?" The second act then started with a reprise of the second half of the number. The show was never again performed that way.
The half-reprise has clearly been edited in from another performance than the one heard on the rest of the recording. We can tell that the rest of this recording was not made at that first preview for several reasons, starting with the fact that it's clearly Arnold Moss as Weismann on this recording, but Moss didn't join the cast till a couple of days later.
We think that the half-reprise probably wasn't recorded at the first preview. It seems to just be an edited-down version of a complete performance of the song. Although three live recordings of the Broadway run (including this sound-system recording) are in cicirculation, the edited version of "Who's That Woman?" doesn't come from any recording that we've found. The half-reprise seems to be from an audience recording so it's clearly not edited from the performance of the song on the sound-system recording proper. And it doesn't match up with either the performance from Dec. 18, 1971, nor with the performance from April 5, 1972.
One oddity of the half-reprise performance is that the taps are much less loud than any of the other live recordings we have of the show.
Fixing a date for this performance has proved elusive. It has circulated with various dates affixed to it, none of which seems to be right based on the evidence within the performance. Our best guess at this moment is that two New York preview performances were edited together, though if that's the case, it remains puzzling why "Waiting for the Girls Upstairs" is incomplete and why a different version of "The God-Why-Don't-You-Love-Me Blues" wasn't used.
