I think this musical should be about a young single woman named Abbey who lives downtown, It can be kind of like Sex in The City only with one person who talks to herself a lot instead of 4 women who talk with each other. And a running gag could be her saying if they made a musical about her, it would be called Downtown Abbey and she bets many people would come to it thinking it would be a stage adaptation of Downton Abbey. And then she breaks into the big 11:00 number "Not What You Thought It Would Be."
Maybe Disney can build a replica of Downton next to the Harry Potter land and they can do a theme park musical version.
