We used to do this song for the annual food co-op benefit in Michigan, followed up with "Sweeny Todd" of course:

THE VEGETABLE SONG
(Words and music by Carl Martin © As sung by Steve Goodman on Somebody Else's Troubles)

It was late last night, by the pale moonlight,
All them vegetables gave a spree;
They put out a sign, said "Dancin' at Nine"
And all the admissions were free;
There were peas and greens and cabbage and beans,
It was the biggest crowd you ever did see;
And when old cucumber, struck up that number,
You should have heard them vegetables scream!
Oh, little turnip top was doin' the backwards flop,
The cabbage did the shimmy, she couldn't stop,
The little red beet, shook it's feet,
And the watermelon dived to the cockeyed beat;
Little tomato, agitator,
Shook the shimmy with the sweet potato,
And old man garlic dropped dead of the colic,
Down at the barnyard dance.
