It would be amusing if Manhattan Concert Productions secretly coordinated with several Broadway actors, so that they all simultaneously announced "I am the Scarlet Pimpernel!" "No, *I* am the Scarlet Pimpernel!", a la Spartacus/Blackadder. (Although no doubt this would backfire in real life, due to fans feeling betrayed etc.)
Maybe they should bump Corey Cott up to the lead. I imagine he would be good, and at least they know that he's available.
