Here's what I have. It's a Texas version of Springield Mountain:

RATTLESNAKE MOUNTAIN

On Rattlesnake me-y-mountain I did de-y-dwell,
And I've-a got a ste-y-story I'm a-gonna te-y-tell.
Come my root eye root eye roo.
A nice young me-y-man in the month of me-y-May,
Went down to the fe-y-fields to mow his he-y-hay.
Come my root eye root eye roo.

He had not mo-y-wode all around the fe-y-field,
'Till a rattle-copper sne-y-snake come and bit him on the he-y-heel.
Come my...
He jumped up he-y-high and danced all a re-y-round,
But the pizen ste-y-struck and he fell to the ge-y-ground,
Come my...

Now Johnny he-y-had a nice young ge-y-girl,
Her name was se-y-Sal and she was a pe-y-pearl.
Come my...
Now Sal she ce-y-came into that fe-y-field,
And sucked the pe-y-pizen out of his he-y-heel.
Come my...

But Sal she he-y-had a rotten te-y-tooth,
And the pizen ste-y-struck and killed them be-y-both.
Come my...
So all you ge-y-guys a warning te-y-take,
And don't get be-y-bit by a pizen sne-y-snake.
Come my...

You folks take we-y-warning and don't ge-y-go,
Like Johnny de-y-dear out for to me-y-mow.
Come my...
The me-y-moral: when in love don't pe-y-pass,
Too near to pe-y-patches of high ge-y-grass.
Come my...
