Because it runs through my head sometimes

Garrison Keillor sings this occasionally as Lefty-the-Cowboy on Lives of the Cowboys on PHC.

And both Theresa Brewer and Marlene Dietrich have recorded it which would be quite the study in contrasts.

You’re the cream in my coffee
From the show "Hold Everything" (1929)
(B.G. DeSylva / Lew Brown / Ray Henderson)

You’re the cream in my coffee,
You’re the salt in my stew;
You will always be my necessity--
I’d be lost without you.

You’re the starch in my collar,
You’re the lace in my shoe;
You will always be my necessity--
I’d be lost without you.

Most men tell love tails,
And each phrase dovetails.
You’ve heard each known way,
This way is my own way.

You’re the sail of my love boat,
You’re the captain and crew;
You will always be my necessity--
I’d be lost without you.

You give life savor,
Bring out its flavor;
So this is clear, dear,
You’re my worcestershire, dear.

You’re the sail of my love boat,
You’re the captain and crew;
You will always be my necessity--
I’d be lost without you.
