Thomas first saw Terence the Tractor
Ploughing in a field one day
And he said, "My oh my, you do look funny
Where are your wheels, are your wheels, are your wheels?
How ever do you move along?
You really do look funny."

"Don't be so rude," said Terence the Tractor
"I don't have wheels like you
Because my caterpillar tracks are so much better
And I can go anywhere, anywhere, anywhere
I don't need rails like you
One day I will prove it, show you how I do it
Then you will understand..."

That you don't judge a book by its cover
Don't make your mind up too soon
Things aren't necessarily
Always what they appear to be
Don't judge a book by its cover
Don't make your mind up too soon
Never, never, never, never, never, never, never, never
Never judge a book by its cover

Sure enough, one winter's day
When the snow lay deep and hard
Thomas got stuck, he was in trouble
And who do you think came along, came along
And rescued him that day
The snow didn't matter to Terence the Tractor
Now Thomas understands...
That you don't judge a book by its cover
Don't make your mind up too soon
Things aren't necessarily
Always what they appear to be
Don't judge a book by its cover
Don't make your mind up too soon
Never, never, never, never, never, never, never, never
Never judge a book by its cover

Don't judge a book by its cover
Don't make your mind up too soon
Things aren't necessarily
Always what they appear to be
Don't judge a book by its cover
Just remember the rule
Never, never, never, never, never, never, never, never
Never, never, never, never, never, never, never, never
Never judge a book by its cover!
