It was the summer of 1996.
The ASCAP clamped down on much more than "This Land is My Land" it also included "God Bless America" and all 4 million of their other copyrighted songs, yep "Happy Birthday" was in there also. However, camps that were accredited with the American Camping Association (ACA) could purchase unlimited use for the summer season. The fee $257. After all....the camps charged fees...it is only fair that the writer's of "movement songs" and all others should recieve their fair share of their "intellectual property."

God Bless the Lawyers (and doctors too)
