As much as I have issues with this production, I wouldn't really say the score was "mucked with." I mean, the nightmare was cut, which yes, that was very mucked with, and really pisses me off. I think the only other thing that really bothered me was the removal of the distorted "America" that plays during the rape, here, the Mambo just continues.
The smaller changes I noticed that didn't drive me crazy...the transition between the Cha-Cha and Jump used to be Promenade, now it's the Mambo, which I actually prefer the slowing down of and contrasting of.
Let's see...other small changes I noticed is the removal of a one-measure drum solo in Jet Song, the "Pow" at the end, there is new music put before the Rumble while the set goes into place, people seem to like that, the Entracte was cut a bit.
But that's it. Thank god, the Tony solo is back in "Balcony Scene" so...the score could have been mucked with much more than it was, and for that, I'm grateful.
"If there was a Mount Rushmore for Broadway scores, "West Side Story" would be front and center. It snaps, it crackles it pops! It surges with a roar, its energy and sheer life undiminished by the years" - NYPost reviewer Elisabeth Vincentelli
