Simpler version (Lancs UK, 1950s):

There was a princess long ago,
Long ago, long ago,
There was a princess long ago,
Long, long ago.

The princess lived in a big tall tower,
A big tall tower, a big tall tower,
The princess lived in a big tall tower,
Long, long ago.

A wicked fairy cast a spell..

She fell asleep for a hundred years...

A big tall forest grew around...

A handsome prince came riding by...

He chopped the trees down one by one..

He woke the princess with a kiss..

So everybody's happy now...

We all join hands and take a bow,
Take a bow, take a bow,
We all join hands and take a bow,
Long, long ago.
