"It ain't over until the fat lady sings" means not to presume to know the outcome of an event in progress, when a situation is or appears to near its conclusion. The phrase cautions against assuming an event's result or outcome.
The phrase is a reference to traditionally heavy female opera sopranos. The "fat lady" was usually presented as a very buxom woman. The farewell scene for "Broom Hilda" (Brünnhilde in German) in Wagner's opera Der Ring des Nibelungen lasts almost twenty minutes, leading directly to the finale. As the opera's final part suggests the end of the world —or at least the world of the Norse gods— in a very significant way "it is [all] over when the fat lady sings."
A reader asked about prior references here to the fat lady, related to the USA's presidential election and current status.
The Committee says:
"As the many of you know, a great effort has and is being made to pretend the recent USA presidential election was legitimate. It was far from it, however the forces behind the twist have successfully concealed their acts and threats. The risks of leaks have been plugged with great fear, so you will not hear about them, either the leaked information or efforts to prevent release.
To understand what has happened, we appeal to American voters and others also, with a memory of many such presidential elections. When did the counting require so many days? When did the apparently losing side rebel to such extent or degree? Why was every court case dismissed without a public hearing of the evidence? Where is this evidence? Why was the elected parliament so quick to blame to outgoing president long before any reasonable investigation could be made? Why was nearly every poll wrong, except for the presidential race?
Mr. Trump is the legacy of the Obama Biden administration; Trump could never have been elected without them. Because he was not a politician, he was underestimated as a candidate however the true mistake occurred among the HCPs who have grown arrogant with the manipulated populations upon which they prey. They were handed a nasty voter surprise when Trump was elected, and used their employees in the political realms to distract the population while they engineered an election result to ensure Mr. Trump's removal.
You who might have voted for Biden, did so purely because of policy and dislike. You want different things done with government and you dislike Mr. Trump. You did not vote for Mr. Biden because of his appeal, record or ability and you were stuffed with a president who serves not you, despite rhetoric and appearance otherwise.
The American voters have essentially rolled over and accepted the election coup d'etat. The highly partisan press has orchestrated a concert of opinion about Mr. Trump which is pure fabrication.
You are all observing the censorship, given the label of mis- & disinformation. If such is offered, the answer is to offer the correct information, including explanations for both. This is rare and sadly, free speech is stepping backwards, to the short term glee and joy of people who will pay the heaviest price for it when time comes to eat what is being served.
Your questions we welcome."
