Whelk or Flounder?

Way down underwater, crawlin' slowly on the seabed,
Is a large marine snail, whelk, upon which many French are fed,
While we say flounder tastes fine.
Well now I have reached decision time:
Will it be whelk or flounder
That I choose from the à la carte?

(Hmm? hmm? hmm? . . .)

Whelk or flounder, whelk, whelk or flounder? (7x)
Whelk or flounder I choose from the à la carte?

You see, I've got a French wife
Whose hauteur disarms any man.

(Haut-hauteur)

And her unyielding view on haute cuisine is
Strong as her New Wave stance.

(Au-auteur)

Flounder I wanted to try,
But she was givin' me the gimlet eye.
I chose whelk over flounder—
Topped it off with à la crème tarte.

(Um! Um! Um!. . .)

Whelk or flounder, whelk, whelk or flounder? (ad infinitum)
Now she won't hound me, I hope, this sangfroid tart.
