Witch's demise / get it into your head

Look at the children run
They're having so much fun
I've never heard so much laughter
Crying out that they've won
Saying the Lion's undone the witch
And then He unmasked her
Then He cast her to disaster
What a Master!
She never stood a chance
Why did she stay?

Get it into your head
Now that the snow has fled
Now that the witch is dead
The danger is gone
Aslan has set us free
Oh what a mystery
Lies in the history
Here in Narnia

No tears of sorrow to shed
Now that the snow has fled
Now that the witch is dead
There's peace in our hearts
It's not an if or a maybe
Oh what a mystery
Aslan has set us free
Here in Narnia
