From deep in the sock hanging by the fireplace comes, in the voice of Burl Ives:

Once a lonely caterpillar sat and cried,
To a sympathetic beetle by his side.
"I've got nobody to hug,
I'm such an ugly bug."
Then a spider and a dragonfly replied,
"If you're serious and want to win a bride,
Come along with us,
To the glorious
Annual ugly bug ball."
Come on let's crawl
Gotta crawl, gotta crawl
To the ugly bug ball
To the ball, to the ball
And a happy time we'll have there
One and all
At the ugly bug ball
While the crickets clicked their tricky melodies
All the ants were fancy-dancing with the fleas
Then up from under the ground
The worms came squirming around
Oh they danced until there legs were nearly lame
Every little crawling creature you could name
Everyone was glad
What a time they had
They were so happy they came
Everyone was glad! What a time they had!
They were so happy they came!
Come on let's crawl
Gotta crawl, gotta crawl
To the ugly bug ball
To the ball, to the ball
And a happy time we'll have there
One and all!
At the ugly bug ball.
Then our caterpillar saw a pretty queen
She was beautiful in yellow, black and green
He said, "Would you care to dance?"
Their dancing led to romance.
And she sat upon his caterpillar knees
And he gave his caterpillar queen a squeeze
Soon they'll honeymoon
Build a big cocoon
Thanks to the ugly bug ball
Come on let's crawl
Gotta crawl, gotta crawl,
To the ugly bug ball
To the ball, to the ball
And a happy time we'll have there
One and all!
At the ugly bug ball!

After this ditty, the bat wriggled around till their head popped out of the sock, which rather miraculously did not fall into the fireplace. Feeling peckish after that version of Johnny McAdoo, are ye? came from a rather piratical-seeming parrot perched above the bust of Pallas Athena by the pot-boy in the corner as the Devil took a chair...
