AS TIME GOES BY
Words and music by Herman Hupfield, ©1931
Originally sung by Frances Williams in the Broadway musical "Everybody's Welcome", 1931.
Also sung by "Sam" (Dooley Wilson) in the film "Casablanca", 1942.

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

You must remember this
A kiss is still a kiss
A sigh is just a sigh
The fundamental things apply
As time goes by

And when two lovers woo
They still say, "I love you"
On that you can rely
No matter what the future brings
As time goes by

Moonlight and love songs
Never out of date
Hearts full of passion
Jealousy and hate
Woman needs man
And man must have his mate
That no one can deny

It's still the same old story
A fight for love and glory
A case of do or die
The world will always welcome lovers
As time goes by
