Here is a clip from a song that didn’t make it into the movie.

What movie and what was the song?

Clue: Ilse.

This day and age we’re living in
Gives cause for apprehension
With speed and new invention
And things like fourth dimension
Yet we grow a trifle weary
With Mr. 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.
