Jogging Mike Perry's memory as to the article in which Ron Bopp listed
movies in which mechanical music of all kinds could be seen (mentioned
in Mike's 17.01.25 MMD posting), the Carousel Organ Association of
America's journal, Carousel Organ, carried an article in issue #60 by
Ron, titled "Mechanical Organs and the Motion Picture."

But Ron Bopp is still alive and with us.  So it is best to get
confirmation from Ron as to whether this is the article Mike Perry is
thinking of.  Ron's email address is rbopp1@tampabay.rr.com.geentroep
(of course, delete "geentroep" when using it).
