All that can presently (June 2019) be gleaned from sheet music covers and by internet searching is that Bernard B. Brin has 6 works published between 1915 and 1924.
Of ragtime interest is Jitney Bus Rag
(1915) published by Brin Music Co.
, Seattle, Washington, USA.
Surfers are welcome to contribute information about this composer.
, bandleader of Vince Giordano's Nighthawks, sent me three titles of Brin's works on 23.12.2017. Many thanks Vince!
