I have a copy of QRS roll 1324, "My Mammy" (Young/Lewis/Donaldson),
Irving Berlin 1920.  This roll is a different arrangement than the
one found on an Automatic "G" roll issued in 1920 (the number and
label are gone).  On this particular tune, there is _no way_ that
a QRS master was used for the "G" roll performance.

I wonder how many other pieces this is also true of, and if the use
of QRS masters for orchestrion rolls has been widely overstated and
inflated?
