sounds to me very like Black Sabbath. Can't remember the name of the track but the first line is something like "I'm not the kind of person/you think I am"
I agree with bobbobley. Sounds like Black Sabbath (also the song title, and the album I think). The bell is a ghostly single chime each time and there is rain & thunder. Goes on like that for a while then Ozzy does his mournful bit.
Thanks people, I've checked out all these but none of them are the one. The intro is similar to "Black Sabbath" but the actual song was more upbeat. I thought it might be something about a devil in a black dress but the only song I could find about that was by some group called Jack off Jill, and this definitely wasn't the song.
