Saw the matinee yesterday. The staging is one of the more impressive things we have ever seen.
Show ran just over 3:15 from lights off to bows, so they seem to have tightened things up a bit, we were told "3 and a half hours" upon entering the theater.
A few empty seats in the Audience Left section, a few more (10?) after intermission. Maybe folks thought lights on after 2 hours was the end of the show?
Things they don't need that could make the show tighter: Eliminate the audience participation part. That will save the 5-7 minutes to chose and "dress" the volunteers. The song they sing with the audience sitting on the floor could totally be eliminated and wouldn't cost a thing plot-wise.
To answer the last question, the bust is of Herman Melville and they do speak to him now and then, and not in a nice way. Did they need approval of the estate to stage this?
A question of mine, regarding the Queequeg character, in his introductory song he tells us he will tell us about his place of origin in a later song. Did they cut that later song? We thought he was the best actor on the floor, but didn't feel like the cast had much passion. Could be the length of the show, with an early matinee after a long evening performance the night before.
