Hi everyone,  Can any of you answer any of the following questions?

1. Who was 'Randolph' who recorded for the Gulbransen Music Roll Co.?

2. Was there ever a recording piano (i.e., a player that was used to
record rolls) that could be mistaken for a normal player piano without
close inspection?

3. Would re-editing QRS and other companies rolls, to add many extra
notes, and releasing them on your own company's label without credit,
be legal, and/or an effective way of getting around mechanical music
copyrights in the 1920s?

Regards,
Robert Perry
