[78-L] Nobody Knows You When You're Down And Out - who was the composer?

[Tim Huskisson]

After reading of the death of Pinetop Perkins, my attention turned to his
inspiration, Pine-Top Smith. I had not realised that P.T. Smith had recorded
'Nobody Knows You When You're Down And Out' for Vocalion some four months
before Bessie Smith.

But after searching the On-Line Discographical Project, I discovered another
version by a vocal group - 'Aunt Jemima Novelty Four'.
If the sources are reliable, it would seem Bessie Smith's recording was made
on May 15, 1929 and the other two versions, BOTH on Jan 1, 1929. 
But who wrote the song? My British Parlophone issue gives the composer as
'Jimmy Cox' (who I can find no information about), and (for Bessie's
version, the On-Line Discographical Project indicates IDA COX-B.FELDMAN were
the composers. Were Jimmy and Ida related?

But the 'Aunt Jemima Novelty Four' version was evidently composed by Fugitte
- Burns. (Who were they?). Rust's 'Jazz Records' shows some 1929-1930
sessions for Brunswick and Gennett by vocal duettists 'PETE & REPEAT' (?
___Fugitte and ? ___Bruns).

To confuse the issue further, REDHOTJAZZ.COM indicates that Pine-Top Smith,
himself, was the composer!

Can anyone here shed any more light on the history of this song?
Many thanks, 
Tim Huskisson
