Just watching an old re-run of 'Green Acres.'

In the opening scene, their hired hand is singing a song
called 'Shed a Tear for Gertrude' (at the bottom of the
sea). The verse was about a woman who gets washed overboard.

Then Oliver (Eddie Albert) asks what he's doing, and he says
he's singing an old folk song he learned in his home towns.
Oliver allows that when he was in college he traveled around
collecting and recording folk-songs. "Even wrote some" he
said. The rest of the plot revolves around a local legend in
Hooterville, Molly Turgis, about home Oliver determines to write
a ballad. Molly, it seems, is a bit of a curse...

Anyway, I can find no hint of 'Shed A Tear for Gertrude' as a
real song. Anyone hear of it?

Anybody else remember this episode?
