The other day after work I bought a two cd set of Bach organ music. The first two tracks are, of course, the requisite Toccata & Fugue in D minor. Even if you don't what it is you've all heard it, at least the opening strains of it: think horror movie, or Munsters. I think they used it often. I have to chuckle over the Toccata, though. Every single disk I looked at that dealt with Bach's organ music had at least some form of it recorded be it parts or the whole thing. The other thing about the whole Toccata thing is that Bach wrote them as a way to "test drive" organs. He put the organs through their paces to see what they could do. That is one reason why they are so dare i say it: "fancy."
What's even funnier is this: as I'm driving down the road, my windows are open and I have Bach going... I've gotten some interesting looks from people beside me at traffic lights.
