Here's an old German film with a Glockenspiel clock performance at
about time 1:20 -- https://www.youtube.com/watch?v=CJA7pOTy-JE 

So far we've learned that the melody is "Ein Mädchen oder Weibchen"
(A girl or a woman) from Mozart's "The Magic Flute".  Now -- and this
is a long shot! -- German readers, take note!  Does anyone know where
this animated clock is located?
