Hi,
I hold the copyright to "Waltzing With Bears". It was submitted to the copyright office in 1986 for me by Robbie Clement of Tomorrow River Music.    At that time, Robbie informed the US Library of Congress copyright office of the Dr. Seuss song, but the copyright office determined at that time that "Waltzing With Bears" and the Dr. Seuss song were substantially different works, and therefore "Waltzing With Bears" deserved and was given its own copyright. Any uncertainty about copyright, including that involving Holly Tannen, occurred prior to this resolution by the Library of Congress. There is really no uncertainty about it. For about eight years royalties were sent to me through Robbie, but for about the last ten years royalties are now sent directly to me. Please contact me for further information.
