Spoilers ahead if, like me, you don't want to know about changes before seeing it:
They cut Embassy Lament and the first part of Endgame. I love them musically but totally get it dramatically. Svetlana has a new-to-me song, He Is a Man, He Is a Child, which I guess was added in a previous Swedish production. Three songs precede Merano now, opening with Difficult and Dangerous times - quiet apropos given the book's tilt away from chess towards the Cold War. Someone Else's Story is now the 10 o'clock number (shows don't go to 11 anymore).
