The song If I Only Had A Brain is performed by Wizard Of Oz .
I could while 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 every riddle
For any individual
In trouble or in pain
With the thoughts you'll be thinkin'
You could be another Lincoln
If you only had a brain
Oh, I could 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 nothin'
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
Gosh, it would be awful [Incomprehensible]
To reason out the reason
For things I can't explain
Then perhaps I'll deserve your
And be even worthy of your
If I only had a brain
