One nice round I heard a bunch of Girl Scouts singing as they passed in a small flotilla of canoes was

Our paddles clean and bright
Flashing like silver,
Swift as the wild bird flies,
Dip, dip, and swing and back;
Dip, dip, and swing.

Then, of course, there were Boy Scout camp songs, such as

Do your ears hang low?
Do they wobble to and fro?
Can you tie them in a knot?
Can you tie them in a bow?
Can you throw them over your shoulder
Like a continental soldier?
Do you ears hang low?

Not Mozart, but fun stuff, especially if you're a kid.
