There’s the kernel of a good show in this copycat Hamilton: Treason the Musical reviewed

Copycat Hamiltons are everywhere. Lin-Manuel Miranda led the way by turning an unexamined corner of history into a smash-hit show. The latest antique subject to become a musical is the Gunpowder Plot of 1605. The script, by Ricky Allan and Kieran Lynn, ought to include those words in the title because they give vital data about the location, the historical period and some elements of the story. It’s a priceless asset. But they’ve tossed it aside and plumped instead for the vague, unsuggestive ‘Treason’. The best-known figure in the conspiracy, Guy Fawkes, gets a mention — as ‘Gwee-dough Forks’ — but doesn’t feature as a character. Another puzzling decision. Writers of musicals should locate the story’s best features and build on them. To discard them carelessly is bizarre and foolhardy.

The show opens with some aridly tragic warbling between a plotter called Thomas and his tearful wife, Martha. Thomas’s surname happens to be Percy and, sure enough, he receives ‘no mercy’.
