"Trying to shove these songs into the show score is questionable to begin with, and it’s done here with a consummate lack of skill. Fredrika’s 'Glamorous Life' is broken up into sections that are interrupted by bits of the original version sung by Desirée, Madame Armfeldt, and the Liebeslieder singers, while 'My Husband the Pig' is stuck into the middle of Carl-Magnus’s 'In Praise of Women.' It’s surprising that Sondheim allowed any of this; the 'Glamorous Life' conglomeration, in particular, is hard to listen to because it contains several bizarre modulations of key. "
Yes. Both sequences just about worked in the theatre - 'My Husband the Pig' in no small part because Patricia Hodge gave such a brilliant acting performance as Charlotte - but neither is an improvement. My understanding is that Sondheim allowed this production to try these changes, and has never allowed them since; he seemed happy enough when he got up onstage at the curtain-call at the final performance (I was in the second row), but of course that could have been because he knew he'd never have to suffer this version of the show again!
