Answer :
When the theatre was full, the duke left his door-attendant job and entered the stage via a back door.
He spoke briefly before the curtain and praised the tragedy, calling it the most exciting one ever. He continued bragging about the tragedy and Edmund Kean the Elder, who would play the main principal role. Finally, when he had raised everyone's hopes to an appropriate level, he rolled up the curtain. The duke then lowers the curtain, bows to the audience, and announces that the performance of the great tragedy will only last two more nights due to pushing London engagements, where Drury Lane's seats are already completely sold out. He then gives them another bow and asks for their help in spreading the word about the play to their friends so they can also go see it.
