Now, the way my sister used to sing it was more like this:

HAGALENA MAGALENA

CHORUS
Hagalena Magalena
Whoopensteiner Walkenheimer
Mooga Mooga Mooga
Was her name.

She had long hair down her back
The ends were yellow and the roots were black

A ten-ton truck hit Magalene
They had to buy a new machine

She had two teeth in her mouth
One pointed north and the other pointed south

(from memory - I'm sure I'll remember more verses later.)
If I recall correctly, my sister learned this at Camp Singing Hills, the camp of the Girl Scouts of Racine, Wisconsin. My sister's camp name was Frankie. In the 1980's in Sacramento, I met a woman who had known my sister as Frankie, not as Mary Ann.
I suppose that in all fairness, I should ask my sister to drop by and comment. I suppose that in all fairness, I also should admit that there may have been a few things that I did to drive her crazy, too....
I think there was a verse about Seven-Up, but I can't remember that one.

Let's see if I can remember or remember and extrapolate some others:

She had two eyes in her head
One was yellow and the other was red

-Joe-
