We all started singing this because it mirrored our sentiments and is so easy to modify. Now it's going around the world as rapidly as the new, speedier forms of communication can transmit it. Thanks to all of you who have kept it going by singing it, teaching it and writing new verses. Keep it up!

Thanks especially to Charlie Baum and Lisa Null who have pointed out that its dissemination is a perfect and very speedy example of folk process.
