I saw the original 42 times (I know ...) and remember they tried moving things forward for a while (moving up people's birth years), but after a while, seemed to realize there were so many changes necessary (like referring to The Ed Sullivan Show) that they froze it and kept it in a more-or-less permanent 1975-76. The original was so determined to adhere to its "Time: Now, Place: This Theatre" setting that the opening night in Boston was always something like eight weeks from the actual date of the performance.
They did update the Troy Donahue reference, but I'm damned if I remember who it was. I do kind of recall it not scanning. |
