With no movement other than drums being beaten, people soon lose
interest in organs after admiring the art work and carvings.

A couple of street organ owners here in the Pacific Northwest have
followed my lead in suspending small paper or cloth rectangles over the
throat of the organ pipes.  They flutter when the pipe is active and
dance about across the display of pipes.  It fascinates the onlookers
and adds to the attraction.  I use them on both my Pell and Raffin
organs.
