Funny this thread would be resurrected today when I was just contemplating trying to work out a conversation setting of Cuckoo's Nest or a bawdy songs workshop.
The particular Cuckoo's Nest song I'm thinking of is the one done on the Morris On album.

The DT lyrics have what I think of as the chorus as the second verse:

Some like a girl who is pretty in the face
and some like a girl who is slender in the waist
But give me a girl who will wriggle and will twist
At the bottom of the belly lies the cuckoo's nest

But it's fairly obvious the other verses are alternately written from the male or female point of view, and I sing the chorus in between (each pair of He comments, she responds) and the last sort of narrator's verse...

In the great male/female conversation song list, I highly endorse anything Lou & Peter Berryman have written - but Crab Canape is just -the best- for high contrast.

Versions of "THE DEVIL'S NINE QUESTIONS" would work well as a conversational duet.
