If I remember right, in the Doris Day film "By The Light Of The
Silvery Moon" there is a scene in the living room where she plays
a piano roll on a later model Duo-Art grand piano.

I only remember the scene because the spool box switch was set to
Duo-Art, they were playing a standard 88-note roll, and they filmed
it to look like she was pumping the piano.
