Isabel:
They say happiness is a thing you can't see; a thing you can't touch; I disagree.
Happiness is the folly of fools; pity poor me, one of those fools.
Happiness is staining beside me. I can see him, he can see me.
Happiness is whatever you want it to be.
Isabel and Scrooge:
Happiness is a high hill, will I find it? Yes I will!
Happiness is a tall tree, can a climb it? Wait and see!
Scrooge:
They say happiness is a thing you can't see; a thing you can't touch; I disagree.
Happiness is the folly of fools; pity poor me, one of those fools.
Happiness is smiling upon me; walking my way, sharing my day.
Happiness is whatever you want it to be.
Isabel and Scrooge:
Happiness is a bright star, are we happy? Yes we are!
Happiness is a clear sky, give me wings and just let me fly!
Let me fly!
Just let me fly!
Let me fly!
Just let me fly!
Let me fly!
~Musical interlude~
Isabel and Scrooge:
Just, just let me fly.
