My impression of Reiter's mention of Goldweber in the review was that she was surprised that there wasn't an official (with registered trademark) Balanchine stager to which the production was credited. There wasn't anything else in the review that suggested there was anything amiss with the staging. She liked some performers more than others, but a sense of spontenaiety and confidence is not something a stager can force from a dancer.
Exactly, Helene. I got an email this morning from Reiter, telling me that, in response to her query, she had received a letter from the Balanchine Trust that the stager was Paul Boos and that Mark Goldweber had "maintained" the production since 2004, and asking me to put up a note at the bottom of her review to this effect.
