Beggar's opera
The Beggar's Opera introduced to theater the ballad-opera and an immortal cast of characters. The Peachums, employers of a company of pickpockets, shoplifters, and thieves, raised their daughter Polly for finer things, but she has done a dreadful deed. She has married for love. Her husband is Macheath, so exquisite a robber he might have been a lawyer or lord, and so devoted to matrimony that he has two or three wives already.
