I think it would be cool if they brought this back for a strictly limited run every few years or so. This would (A) give Roundabout a definite income and continued availability at their Studio 54 site, both of which would (B) allow them to keep producing other works. And it would (C) continuously allow new (and old) audiences to experience a fantastic, entertaining, important show.
You know, it would be like, "OK, it's been 4 years... time for another 6 months of 'Cabaret.'"
"I just want a story and a few good songs that will take me away. I just want to be entertained. I mean, isn't that the point?"
