Bennet,

How about "We're Going to Keep on Walking Forward" by Judy Small. It's a "zipper song," will take any verses you put into the form:

We're going to keep on walking forward,
Keep on walking forward,
Keep on walking forward:
Never turning back,
Never turning back.

So you can add things like

"We're going to work for peace and freedom..." etc.

Cheers!

Sharyn
