Perhaps as time goes on Kumbayah isn't quite as over done as we think. A couple of summers ago I took a group of kids on a Church sponsered mission trip where we met up with kids from churches from through out the mid west US.
One evening the activity was a simulation on economic injustice. As the upper 5 percent were seated and waited on with soda and popcorn directly infront of the movie screen the next 10% sat on the floor behind them and were told to be quiet and not disturb the people in front of them. They had a handful of popcorn and a juice box.
The "masses" were then brought to the back of the room and basically bossed around and given nothing.

The kids from my rather liberal eastern suburb had done this type of thing before and all began assorted protests.... But when it became clear they needed to organize the other 50 kids to acomplish anything I suddenly heard ... "Look we'll march up to the front singing Kumbayah..." "What's that ???" Not a single other Church group new the song. They ended up singing Row Row Row your boat because it was the only song they all knew.
The actions were louder than the words. But part of me wishes the other kids had known the words.....
