Where/how/when: Elementary music class in early 1980s, taught by elementary music teacher

What I remember:

Down by the river mama she wash my shirt. She like to use a stone to knock out the dirt. The river is shallow. The kids knock about. And when it time for supper mama have to pull them out. Don't go 'way, don't go 'way mister river. Won't you stop and play as you travel out to sea?

Thanks!
