'London Bridge Is Falling Down' (also known as 'My Fair Lady' or 'London Bridge') is a traditional English nursery rhyme and singing game, which is found in different versions all over the world. It deals with the depredations of London Bridge and attempts, realistic or fanciful, to repair it. It may date back to bridge rhymes and games of the Late Middle Ages, but the earliest records of the rhyme in English are from the seventeenth century. The lyrics were first printed in close to their modern form in the mid-eighteenth century and became popular, particularly in Britain and the United States in the nineteenth century.
