Just another love song?

What do you think of when you hear this?
What imagery comes to mind?

Monsters, vampires and mad scientists were unheard of in the culture of Bach's day.
What do think this masterpiece evoked in your great grandparents?
What/who changed it? Why?
Why was Yvonne DeCarlo chosen to play Lilly Munster? Why did Lilly and Morticia Adams have such refined manners?
Was high culture purposefully smeared as something freakish and monstruous?

Here is Anna Safka at here finest. Great voice.
