I am an emotional person, but I can still speak the facts. He makes a lot of claims yet most of them are unfounded. The best case he can argue is the John B and even then he can't prove that the song wasn't already in The Bahamas predating the 1903 reference(which by the way I can't find.) As far as I personally have been able to confirm is that of richard le gallienne mentioning in a 1916 article. Which I haven't read as of yet.
