Also presents an emotional arc issue placing Mistoffelees before Macavity. With that presentation, would require the secondary plot issue to be cleared earlier in the story line and leave a spacer peice not associated with the final climax after it.
Misto ends the macavity story line, placing an explanation of who Macavity is after he has been run off slows the story line as its more of a build up peice and not a climax itself. With addressing a cat already at the end of the main storyline they are letting the audience go on a down note compared to ending with the selection.
My opinion. Move addressing earlier (just after Old D to carry on the arc) and add a version of the dance choreography for Jellicle songs to end on high energy.
just wondering if addressing would kill the energy level earlier as well.. Old D is slow enough it should would well in tandom.
