Lyrics:

A long, long time ago
In the land of idiot boys
There live a cat, a phenomenal cat
Who loved to wallow all day

No one bothered him
As he sat, content in his tree
He just lived to eat 'cause it kept him fat
And that's how he wanted to stay

Though he was big and fat
All the world was good to him
And he pointed out on the map
All the places he had been
Cowes, Sardinia, Kathmandu
The Scilley Isles and Sahara, too

Fum, fum, diddle-um di
La la la la, la-la la la
La la la la, la-la la la la
La la la la-la la la

Once when he was thin
He had flown to old Hong Kong
And had learned the secret of life
And the sea and the sky beyond
So he gave up his diet and sat in a tree
And ate himself through eternity

Fum, fum, diddle-um di
La la la la la-la la la
La la la la, la-la la la la
La la la la-la la la

Fum, fum, diddle-um di
Fum, fum, diddle-um di
