I'm looking for the artist/band/song title, of a song that was release in the late 90's.?

I'm looking for the artist/band/song title, of a song that was release in the late 90's I believe. The artist/band use some sort of Darth Vader/Starwars theme as part of this song. ( That I can remember, but I can be wrong) The most famous lyric of the song is " I guess they say it's true, I could never be the right kind of girl for you, I can never be a woman. " The interesting part is that a man sings this song. So if anyone has any idea about this song, please let me know. THANKS!
