"Also I'm pretty sure that bringing back a show that played for 16 years only 3 years after it closes is A LOT different than a show playing for less than 2 years in 1971 and less than a year in 2001."
You're right, it makes more sense to bring back a hugely successful show than one that has flopped twice (the last time only 6 years ago).
"I'm almost certain the original "happy" London production of FOLLIES was a success."
The London production opened July 1987 and closed 7 months later, more quickly than the original Broadway production.
If this concert version does transfer, then it is possible it could do fairly well as Follies has always worked better in concert since people only attend to hear the score and not the book, which is entirely understandable.
