Saw the production on Monday (and Kander sat right in front of me!!). David Loud, the MD, wrote in his note that this production was Kander's ideal version if he were to assemble his favorites from all versions of the show. There were also new arrangements of songs. Tomorrow Belongs to Me was arranged for a full male ensemble, and Married included a new ensemble choral part resembling "Till Tomorrow" from Fiorello. Cool opportunity to see a new splicing of the show with new arrangements, I wouldn't be surprised if this version has a future in some capacity.
Sounds neat, and what a great opportunity for the students! Kander is a lovely man.
I only wish the original three act structure (with two intermissions) had been reinstated and tried again this time. Hal Prince was convinced by George Abbott (foolishly, as far as I'm concerned) to put the show in two acts, resulting in a very top-heavy musical. But perhaps that helped a difficult show succeed commercially, so maybe not so foolish...?
