help please!

Okay – I need help identifying a song/music video. This is what I remember: it is sung by a girl or girl group. It’s 80s-ish. It takes place in a castle where a lady is running around singing. She may or may not have oddly glowing green eyes? I feel like there’s big hair and white lace corset dresses. There may be a monster or a vampire involved. There may be motorcycles. There’s a big fight at the end, and I think someone falls out of a window and lands on stone steps far below. It’s a power-ballad, sad I think. It would make a really, really excellent karaoke song.

Also, it is not this:

Or this (no embedding, sorry; you’ll have to click through for your Meatloaf today),

Or this, though of course it should be, and thank you, MBG:

So – wtf is it? Does anybody know? I may be getting the white dresses/ motorcycles stuff mixed up with some of these other videos – possibly it’s not even a girl singing, and I only think that because the girl is the star of the video – but, arg, driving me nuts. Help pls!
