Here's one we used to do on a Toby show. It's to the tune of "Till We Meet Again," complete with verse.

Our old hen hatched out some little ducks;
She thought they were all her own.
But when the rooster arrived,
He was very much surprised,
And exclaimed in an angry tone:

Madam, you've been deceiving me.
What I see leaves me in a mystery.
You've played me false, you've been untrue;
I'll sigh, I'll cry, I'll be so blue.
Those ducks you've hatched do not belong to me;
You have mixed with the Web-foot family.
So go your way, and sin no more,
Till we meet again.
