That was exactly my point. I remember seeing LITTLE SHOP back in the 80s at the 350 seat Orpheum Theatre in the East Village. If I recall correctly, I paid about $10 to $15 and had a great time -- it was fun, charming, campy little show that at that price had no problem attracting audiences and ran for 5 years. A few years ago, they tried to move it to Broadway and audiences balked at paying Broadway prices for what was basically the same charming campy little show (albeit with a Broadway budget and Broadway production values). Thus, it ended up running less than a year and was a flop.
ROCKY HORROR had a similarly rough time of it. Ideally, if the Off-Broadway market was better, it should have played at a large commercial house downtown where it could have had a better shot at keeping costs and ticket prices down and perhaps done a better job of attracting it's core audience (which was used to paying about $5 to see the film version of the show at midnight movie screenings around the country). Instead, they stuck it in a Broadway house where it spent most of its run on TKTS and surviving on discount tickets until it finally closed at a finacial loss.
Also look at the recent flop EVIL DEAD, yet another campy musical adaption of a bad 80s cult film. Had the show been mounted 20 years ago when commercial off-Broadway was still viable, it probably would have run for a couple of years (at about $15 a ticket). Today, audiences won't pay $70 to be splattered with fake blood at a campy silly downtown kind of show.
So, yes, I wonder about the prospects for a show like XANADU. It probably would have been a hit off-Broadway a couple of decades ago, but will today's audiences plunk down $100 a piece for a campy rollerskating spoof? We'll see.
