Did this with Joe long ago, it's on my wall

"I Cannot See"

The Assistant sings:

I cannot see why you are grieved
What more can honest people do
then be conscientious and pursue
with diligence the art they've received?

When you accept your father as a youth
You'll learn from him what you desire
And if as a man you add your share of scientific truth
Your son can still go higher.
