In the early 18th century, Georgian Britain was a nation openly, gloriously and often shockingly rude. This was found in the graphic art of Hogarth, Gillray, Rowlandson and George Cruikshank, and the rude theatrical world of John Gay and Henry Fielding. Singer Lucie Skeaping helps show the Georgian taste for lewd and bawdy ballads, and there is a dip into the literary tradition of rude words via the poetry of Alexander Pope, Jonathan Swift and Lord Byron, and Laurence Sterne's novel Tristram Shandy.
