Hi List,  There is a wonderful museum with "carillonklokken,
speeldozen, pianolas, orchestrions, straatorgels, dansorgels, &tc."
Well worth a side trip from Amsterdam.  Guided tours are given by
knowledgeable docents.  English is spoken everywhere.

As most of you know, the Netherlands has a rich history in organ
building dating back to the 1400's.  And they love music of all kinds.
