On YouTube several Dutch street organs can be seen and heard.
Not every video has a very high quality, but still... To see
them use the search string Draaiorgels.
A very nice video is http://www.youtube.com/watch?v=D0YXMmQiYZc
There you can see and hear a hand-cranked, quite new, and very
beautiful street organ called "De Freie". The organ is filmed
from the back, so you can see the cranking (which is not as easy
as it looks to be).
The name is derived from Carl Frei, and this organ is built using
the Carl Frei system. So it can be seen as a tribute to the great
musician and craftsman that Carl Frei was. And this organ indeed
is such a tribute.
There is a CD-recording of this organ available. If somebody is
interested just let me know. I'll be glad to be at help.
