This day and age we're living in gives cause for apprehension. With speed and new invention, and things like third dimension. Yet, we get a little weary, with Mister Einstein's Theory, So we must get down to earth at times, relax, relieve the tension. No matter what the progress, or what may yet be proved, The simple facts of life are such they cannot be removed. You must remember this, a kiss is still a kiss, A sigh is just a sigh… The fundamental things apply, as time goes by.
—from Herman Hupfeld’s As Time Goes By, 1931
