Again I am thrilled that you've been kind enopugh to continue a dialogue here and representing your views and I hope that you continue to do so. And again I mean no disrespect, but sometimes your proclamations of what the law is seem misleading. Indeed the idea of parodying all non PD works in the DT would be nore tedious than expunging the material, but the publicizing the intention to parody does not preclude its use as a defense. It is the intent and object of the parody that is considered as a factor. But most of these concerns are settled out of court when rights clearinghouses decide realize that they can somehow strike a deal and make a buck. "Forbidden Broadway" comes to mind. This approach to the problem is perhaps an exercise in futility, but it has something to do with the consideration of just what folk music is and how it is and will be transmitted, and whether it can be categorically squashed because it falls into a grey area of copyright law. Also, the copyright of an arrangement of a PD work does not extend the duration of the copyright of the original work, it merely creates a copyright for that arrangement.
