"London bridge is broken down,
build it up with wood and clay,
wood and clay will wash away,
build it up with bricks and mortar,
bricks and mortar will not stay,
build it up with iron and steel,
iron and steel will bend and bow,
build it up with silver and gold,
silver and gold will be stolen away,
set a man to watch all night,
suppose the man will fall asleep,
give him a pipe to smoke all night, 
my fair lady."
