@Dutchy,
I didn't realize that "tonight will be fine" was a submission. I thought you were just giving me permission to use "Heartache Tonight" as my submission. In that case, my submission is "fine wine." If it's "tonight's the night" I'm supposed to use, then my submission is "Night Must Fall," a play by Emlyn Williams.
Now let me ask you a question. Doesn't one's submission have to be a recognizable phrase or expresssion? "Tonight's the night," for example, is a well-known expression, as well as the title of a song. "Tonight will be fine," however, is not a well-known expression. That being the case, what's the point of the game if we can just make up expressions that nobody ever heard of because they don't really exist?
