Written by John Gay in 1728, The Beggar's Opera is widely considered to be the first musical comedy, and one that pre-empted by about 300 years the current vogue for jukebox productions, which create a plot to fit around hit songs. Gay took some of the best-known tunes of his day, both classical and popular, and worked them into a savagely satirical tale set amongst London's thieves, pimps and prostitutes.
