JRand - In case you missed it in all the excitement, and what excitement it was, does the following (last sentence below) from Broadway.com answer your PAJAMA GAME question?
"In the last few weeks, New York has seen new incarnations of three celebrated '50s musicals. The big deal was, of course, Roundabout's The Pajama Game, and I'm glad to note that it's a success, simply because one never likes to see a first-rate golden-age musical comedy return as a failure.
But unlike many observers who have deemed this production sensational, I found the new Pajama Game satisfactory but unremarkable. True, it makes a better case for the show than did the last two local incarnations, the New York City Opera and Encores! versions. And that's even with Peter Ackerman's book revisions, which substantially alter the characters of Hasler, Prez, and Mae and eliminate such items as Hines' opening monologue and the "Jealousy" ballet."
