Could this possibly be the 1920s/30s jazz number 'Ugly Child' written by George Brunies (a great trombonist)?

Grame Bell's Australian Jazz Band recorded a superb performance of this unusual love song on Aus Regal Zonophone in the 1950s with Roger Bell on vocal.

You some ugly
You some ugly
You some ugly child
The clothes that you wear are not in style
You look like an ape every time you smile

(I forget the next three lines, but it ends...)

There's a curse on your family
And it fell on you
Your teeth are yeller
Who's your feller?
You're such an ugly child.

Quite touching, really and easily adaptable to insult either male or female.   I don't know whether the Bell version has ever been reissued. It should be.
