Hi, I've been looking for this song for years and haven't been able to find it. Please help?

I think it's a song from the 80s. It sounds like pop/rock and has a male singer, plus a couple of female voices in the final chorus. At the beginning and the end of the song, there is a little girl's voice singing in "lalala". There is also a little spoken blurb before the music starts that sounds like this:

"Once upon a time, in a castle in Transylvania, a gambler who said, "No fear to evil", and then, he came." Then there is like a roll of thunder and the music starts, along with the little girl lalala'ing.

From what I can make out, it's a song about vampires. The chorus contains the words "Prince of (the) Darkness", "Man of the Night" and "King of (the) Terror", in that order.

Sorry I can't post more of the lyrics, I can't quite understand them. If anyone has any idea what this is, please tell me.

hi there.
i'm not sure if this will be any help but i was rather puzzled by your predicament.
i tried by typing the lyrics you gave into a search engine, and i came up with a couple of things... but not much... sorry.
anyway, the best i came up with was Iron Maiden lyrics. i'm not much of a fan of them myself but i followed a link to their lyrics page. but i couldn't find much there.
not in relaton to the lyrics you mentioned. there was a song called "Transylvania" but it says on the site that that is an instrumental.
well i doubt this'll help much but maybe it'll jog other ppl memories.
... sorry i couldn't be more help.

I'll look into that. Thank you for your time  :)
