"^ Lestat was also an immediate flop. Finding Neverland is not."
Dracula also had an album recorded for over five years before it was released, and that was with the performance rights already available for licensing.
While it does typically apply to flops, there's a long history of cast recordings being made and not being released. Just this year Stage Door released the 1975 recording of Jack the Ripper, for example. I wouldn't expect Harvey Weinstein to have put out the money to record the OBC and not try to see a return, but it could happen.
