Edited sentence: After The Black Crook (considered the first piece of musical theatre) premiered in 1866 at Niblo's Garden on Broadway (near Prince St), theatres in general moved north in the city.After the Brooklyn Theatre fire in 1876, fire laws drastically changed, for the most part making theatre arson insurance scamming a thing of the past.One reason was theatres were generally made of wood, and unfortunatly most were burned down (all at night).Speculation is theatre owners would burn down the theatre to collect the fire insurance
