London Bridge is falling down,
My fair lady sings.
Build it up with iron and stone,
The city bridge above.
But it's not the same as before,
It's time to tear it down.
London Bridge is tumbling down,
My fair lady sings.
All the gold and silver sheaves,
Are scattered on the ground.
Build a new bridge to the sky,
And take us back to our home.
Soon the old bridge will be gone,
My fair lady sings.
We'll see the river below,
And we'll sing a new song.
Sing a new song, sing a new song,
With hope and happiness in our hearts.
