[Artemisia] Ballad request

[Rebecca Mikkelsen]

Greetings, Bards of Artemisia--I have a request:
I am in need of half-a-dozen or so "Ye Olde English"-style ballads that 
fulfill the following requirements:
Easy to learn to sing
Has a repeating chorus or line that is good for audience participation
Appropriate for children
Not too long (short attention spans)

Part of one of Cote du Ciel's demos at a library involves learning to tell 
stories through music and I would appreciate any help you can give me.

Rebecca
