[78-L] who owns what?

[Malcolm Rockwell]

A few years ago I believe someone here posted a list of which 
multi-mega-corporations now own the performance rights to material 
appearing on many small labels. I'm seeking such a list for the smaller 
78rpm labels. Who owns the Grey Gull stable? Who owns Paramount's 
various labels? Gennett? Early Oriole? You get the idea. I'm not 
particualrly interested as to who owns the label name, but as to which 
corporate entity owns what.
I haven't been able to locate the post(s). A list would be best but any 
help gratefully accepted.
Thanks,
Malcolm
