I had a group of little kids singing and dancing "The Farmer in the Dell" - for a German festival out here. True-Love translated it into German for me. Worked quite well.
I also devised a simple dance to "Ach du lieber Augustin" using words True-Love learned from his German father.

Ach du lieber Augustin
Augustin, Augustin
Ach du lieber Augustin
Limburger cheese

And sausage and weiners
And weiners and sausage
Ach du lieber Augustin
Limburger cheese.

Cheers, Joy
