Hmmm, only 8 years on, but we used to song this as a Girl Guide camp-fire song in England, way back in my long-distant youth! It didn't have many verses, but we used to do banjo-playing impressions! I think we sang it about 3 times over, getting faster each time.
And we might have split the singers in half with one half doing the first part against the others doing the other part.
As another poster has said, the tune was like "Goodnight Ladies" (tho' more syllables to fit in)

Someone's in the kitchen with Dinah,
Someone's in the kitchen, I know, I know,
Someone's in the kitchen with Dinah,
Playing on the old banjo.

And it went oo-plunk eye-plunk fiddley-i-o-plunk
Oo-plunk eye-plunk fiddley-i-o plunk
Oo-plunk eye-plunk fiddley-i-o plunk
Playing on the old banjo.
