Here's one version of it - by Buck Owens and Don Rich.

DIGGY LIGGY LO
Words and music J. D. Miller

Diggy Liggy Li and Diggy Liggy Lo
Fell in love at the fais-do-do.
The pop was cold and the coffee chaud
For Diggy Liggy Li and Diggy Liggy Lo.

REFRAIN: Diggy Liggy Li loved Diggy Liggy Lo.
Everyone knew he was her beau.
No one else could ever show
So much love for Diggy Liggy Lo.

There's a place they find romance,
Where they do the Cajun dance,
Steal a kiss with ev'ry chance,
Show their love with ev'ry glance. REFRAIN

Finally went to see her Pa.
Now he's got a Pa-in-law.
Moved out where the bayou's low.
Now he's got a little Diggy Liggy Lo. REFRAIN
