Following references in several earlier posts, I have obtained some information from both the Montclair Art Museum and the New York Public Library. NYPL. The Museum file on John Allison is quite small, comprised of copies of two oil paintings, two short newspaper clippings about his art work and a program of 24 paintings exhibited at the Feragil Galleries.   The articles are from 1940 and 1941.   The paintings and program are undated, but I believe they were from the 1930s.   Please let me know if you would like additional information.

The NYPL has some of his recordings in one file. In the other file there are 22 boxes of material. Nothing is digital, but in my next post, I will provide some detail about what is in each box. Looks like it covers his entire lifespan which will answer many of the questions raised, and shed a lot of light on this very talented artist.
