Lyrics:

(Scarecrow)
I could wile away the hours
Conferrin' with the flowers
Consultin' with the rain
And my head I'd be scratchin'
While my thoughts were busy hatchin'
If I only had a brain

I'd unravel any riddle
For any individ'le
In trouble or in pain

(Dorothy)
With the thoughts you'd be thinkin'
You could be another Lincoln
If you only had a brain

(Scarecrow)
Oh, I would tell you why
The ocean's near the shore
I could think of things I never thunk before
And then I'd sit and think some more

I would not be just a nuffin'
My head all full of stuffin'
My heart all full of pain
I would dance and be merry
Life would be a ding-a-derry
If I only had a brain
