You very seldom get to hear the tee-up to the familiar chorus (like the beginning of "White Christmas," it gets lost in the rush to the best-known part), so here it is:
This day and age we're living in
Gives cause for apprehension
With speed and new invention
And things like fourth dimension.
Yet we get a trifle weary
With Mr. Einstein's theory.
So we must get down to earth at times
Relax relieve the tension.
And no matter what the progress
Or what may yet be proved
The simple facts of life are such
They cannot be removed
