The Cleveland Index (the one I have courtesy WYSIWYG) is wrong in listing Fenner p. 174 under "Go Tell..." because it is not there. They do list Dett, both variants. The preface to the 1909 edition of the Hampton volume is by Moton of Tuskegee ("for the fifth time we are publishing"), who became leader of the Plantation Songs at Hampton about 1891. Helen Ludlow wrote the preface to the 1891 edition (new songs added- which ones?-, arranged by a Mr. Rathbun) and seems to suggest Fenner was no longer involved. When did he die?
I haven't seen either the 1891 or 1909 editions. Moton states 25 new ones were added in the 1909, 5th edition; he was Commandant in 1909 (probably did not do any editing himself). He credits Prof. Work of Fisk, Jennie C. Lee of Tuskegee and two other schools with the additions (some songs are credited in footnotes to these people but not all). Some songs have footnotes by "Editor," but who was Editor in 1909? It is not stated. When did Dett become Director and was he the Editor? Several references credit Fenner 1909 with inserting "Go tell ...," but should Moton or Dett be credited? What author is on the cover?
The 1927 edition is prefaced by Dett, and has the spiritual on the pages I cited. Dett says that he added several "from his own collection" in the 1927 edition, but, again, which ones? The Appendix, he says, is older arrangements, so those are not his. This is the edition reprinted by AMS and, with a photocopy of the original Fenner, the only ones I have.
All of this is confusing without being able to look at the 1909 (and 1891) edition. Trivia of the most miniscule to most people, but interesting, at least to me.
If you have any more information on the 1909 edition, Masato, I would like to hear it.
