The play was, however, accepted by Rich, and produced at Lincoln’s Inn Fields Theatre. When brought on the stage on the first night, 29 January, 1727–8, Gay’s friends sat in great uncertainty of the event, till they were vastly encouraged by overhearing the Duke of Argyll, who sat in the next box, say: “It will do—it must do! I see it in the eyes of them!” When Polly Peachum sang her pathetic appeal to her parents—

O ponder well, be not severe

To save a wretched wife,

For on the rope that hangs my dear

Depends poor Polly’s life,

and this, to the air of “The Babes in the Wood,” familiar to the entire audience from their nurseries, the effect was magical. The audience broke into a roar of applause, and the success of the play was established.

The plot of the piece was thin and poor, but the people were refreshed, and rejoiced to hear again the old familiar notes of English music. There were sixty-nine airs in The Beggars’ Opera, and nearly every one was an old English ballad or song air. Gay was not himself a musician, but he had his head full of old ballads and their airs, most, doubtless, picked up about Barnstaple or Bideford, and he set to the tunes words suitable to his characters and the dialogue, and then got a German named Pepusch to note them down for him and write a simple orchestral accompaniment and an overture. The author, according to Mace, got the entire receipts of four nights, amounting in the aggregate to £693 13s. 6d., whereas Rich, the manager, after the piece had been performed thirty-six times, had pocketed nearly £4000. It was well said that this play made Rich gay, and Gay rich.

Lavinia Fenton had been tempted by Rich from the Haymarket to Lincoln’s Inn Fields to act the part of Polly in The Beggars’ Opera at a salary of 15s. per week, but owing to the enormous success of the play he raised it to 30s.; and such was the rage of the town respecting her that she was obliged to be guarded home every night by a considerable party of her confidential friends, to prevent her being hurt by the crowd or being run away with. The Duke of Bolton became enamoured of her—took her under his protection, as the euphemism went. The Duke was then in the prime of life, living apart from his wife. “Polly” was not remarkably pretty, but she had a charming manner and a delicious voice. Wharton tells us that he knew her, and could testify to her wit, intelligence, and good manners. “Her conversation,” says he, “was admired by the first characters of the age, particularly the old Lord Bathurst and Lord Grenville.” She and the Duke had several quarrels, and after one very serious explosion he gave her notice to quit the house.

She retired to her room, assumed the costume of Polly Peachum, returned, and presenting herself before him in all the grace and charm with which she had first won him, with tears in her eyes, sang—

Oh, what pain it is to part!
