My thanks to Frank Himpsl for revealing the identities of the
"duo-pianists" "Erlebach and Herzog", "Scott and Watters", etc. 
in MMD 97.03.06.

Here is the label from one of the more "interesting" rolls in my
collection.  Can anyone shed some light on the "nom-de-keyboard" of 
these duo-pianists or the composer:
