Is anybody aware of any updated,or newer information about the real identities and sources of those Record Corporation of America classical Lps ? You know Royale,Varsity, Gramophone,Allegro/Elite,Concertone,et al.
All we have is Ernst Lumpe's original articles,and discographies,which are now at least seven years old.
Has anything been discovered since? There are still a few hundred more left to be identified.
