Glad to be of help, MandolinPaul. It's interesting to watch the 'history' of various songs unfold over time. Some that come to mind are 'Corrine, Corrina' or 'Shenandoah'. Between those two songs alone there's gotta be a few dozen copyrights. And I think it was Mark Twain who said something like 'There's only one thing impossible for God, and that's to make sense of copyright law on Earth.' At times it sure looks that way.
