Sorry mugsy....It's an expression...." It ain't over till the fat lady sings " .
Here's an explanation.
: Whats the origin of the phrase "It aint over till the fat lady sings"
: bluffers' guide to opera.
: the last piece of opera is usually a large female vocalist. opera is apparently so turgid that people try to leave early on the pretext of thinking it is over.
The somewhat Runyonesque dictum, "The opera ain't over till the fat lady sings," is attributed to Anonymous in The Columbia World of Quotations (1996), which compares it to "Don't count your chickens before they're hatched." I think I've heard somewhere, "The fight's not over till the last bell." The saying is not about opera, but about waiting before jumping to a conclusion.
But as regards opera: the last piece in an opera is actually only rarely the fat lady singing an aria. There's usually a big scene with lots of people singing and sometimes moving about (a finale), in which the music may get pretty loud. It may seem a little turgid to some, especially if the opera is by Wagner, but that's not really the right word. Busy, confusing, noisy, might be more appropriate.
