OK, few words in my mind:
They're closing after 666 performances!! HEHEHEHE!! I think that might be why.
And, Tommy Tune once said it best, "Shows used to come in and do their run, not stay in a theatre for 18 years and make it harder for new shows to come in and start running." We should let the shows go in and out. I mean, c'mon, people have been in the show since day 1, they're tired of it.
And, it's not THAT good.
Some people paint, some people sew, I meddle.
