I see in the HAZEL MUNGER BURKE COLLECTION of the Ruth T. Watanabe Special Collections in the Sibley Music Library of the Eastman School of Music, University of Rochester, Akst is credited. Since that collection consists of commercial sheet music, Akst must have been the one credited at publication.

I found a reference to a Frank Warshauer as a composer of “It Isn't Fair” (1933) a radio theme for Richard Himber and I assume it's the same Frank Warshauer. Frank was also the composer, in 1919, of “Rainy Day Blues.”

I also ran across The Charles Anderson Tune List, a loose leaf fake book containing a total of 5729 tunes! An alphabetized catalog is included on the site that includes composer(s), dates and original keys.

I haven't found anything else on “Dinah,” though. Maybe we'll have to ask the HepTune Webmaster about the comment.
