Dear Babs,  Ask Hans van Oost (active in the MMD); he is the secretary
of the board of the "Kring van Draaiorgelvrienden" (KDV), the Dutch
street organ society.

The KDV is producing tapes and CD's with organ music.  So Hans will be
glad to be at help, I think.  And he also will be able to give you some
other sources, as the "Museum Van Speelklok to Pierement" in Utrecht,
and so on.

Bye, Jan Kijlstra
