Musical and Horror, a viable combination?

As a perceptive reader might allready have picked up from my previous entry, I love horror movies, and I'm constantly searching for that thrill, that jolt of adrenaline that let's me know my body is quite convinced I'll snuff it any minute now, while my head knows I'm still safe, comfortably cuddled up behind the everpresent fourth wall. As the perceptive reader might also have found out, I'm also fond of the musical genre. No, it doesn't bother me how everyone suddenly knows the lyrics, and quite often the dance moves. Then again, like in horror, musicals can be good and outright horrible, so not everything is good.

At any rate, I would like to see these two genres combine, mingle, produce viable offspring, if you will. There are a few faintly horror-themed musicals, like Canibal! and, to a degree, Sweeney Todd, but the horror ends up either fading out entirely or taking the backseat to the musical and accompanying drama. The Rocky Horror Picture Show is mostly horror only in name, as it's named after the mute brute Rocky Horror. Of course, it references multiple horror movies of the good old fashioned sort, but it's not quite the same.

What I want to see is a genuinely creepy horror film that is also a musical. I am not quite sure you can actually make a movie like that, but I'm still hoping. The first possibility that springs to mind is a slasher musical. Imagine the scene, one of the early victims walk down a dark corridor to investigate a noise, open a door, and out bounces a confuddled cat (or possibly a ferret, since it's always a cat.) The soon-to-be slasher victim picks up the pet and returns to whatever she was doing, singing about how freaking scary everything is. As the song ends, she is predictably, but of course throughoutly gruesomely, murdered. The whole movie would probably end in some claustrophobic labyrinth setting where the survivor girl and the movies monstrous madman chase eachother, singing a duet (or more like a two-way monolouge while singing, think "My Friends" from Sweeney Todd.)

As I said earlier, I'm not really sure if anyone could, or would, try to make a project like this work, but I guess there's always the faint hope. Additionally, yours truly, being a wannabe filmmaker, would probably have a gander at the possibilities of making Stab: The musical if the occasion should ever arise.
