Cary Fridley must have worked out some words that she likes, because she sings this song on her album "Neighbor Girl." There a generous sound sample on this page. Here's my attempt at a transcription, but there are some gaps:

Now old Uncle Dudy in the shade of a tree,
He played on his fiddle in the key of D.
Now the sheep's in the meadows and the cow's in the corn,
But our Uncle Dudy could ...

CHORUS: Keep fiddlin' on, Uncle Dudy, Uncle Dudy.
Keep fiddlin' on. Just fiddle right on.
Keep fiddlin' on, Uncle Dudy, Uncle Dudy,
Till the old man's gone, till the old man's gone.

Well, hi, Uncle Dudy, how you feelin' today?
... pretty well, ... say
...
But I sure can't handle that fiddle any more. CHORUS

Now Aunt Mina hollered just as loud as she could:
"Say, Uncle Dudy, ... wood."
Well, he kept on a-fiddlin' and he never turned his head.
Well, he never heard a dang word the old gal said. CHORUS
