Well I might as well share my line of thinking re. the hint as I'm stumped..

1: George! Could be a show from the Gorge in George, WA, but none of my searches yielded anything.

2: NYC... kind of an obvious hint and too general? But there's the whole Woody Allen/New York thing in that episode so maybe. Pick your MSG show..

3: 12/4/91 was the original airdate of that episode accordingly to Wikipedia.. and there have been lots of shows on 12/4 ... 94, 95, 96, 99

I agree with @pistilstamen on the timeline re. tones, and @PersnicketyJim is right, is does sound a LOT like a section of that 11/30/97 Wolfman's.

Other thoughts: it's got a bit of a Squirming Coil / Piper vibe with Page on the piano there, a bit of a island flair that could be a Ya Mar excursion.. Have a feeling it's something familiar from 97 that right under our noses.
