It ain't over till the fat lady sings

The phrase is generally understood to be a reference to opera sopranos, who were traditionally overweight. The imagery of Wagner's opera cycle Der Ring des Nibelungen and its last part, Götterdämmerung, is typically used in depictions accompanying uses of the phrase. The "fat lady" is thus the valkyrie Brünnhilde, who was traditionally presented as a very buxom lady. Her farewell scene lasts almost twenty minutes and leads directly to the finale of the whole Ring Cycle.[1] As Götterdämmerung is about 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."

The saying has become so well known that it was the subject of an article in the journal Obesity Reviews.[2]

The first recorded use appeared in the Dallas Morning News on March 10, 1976:[3]

Despite his obvious allegiance to the Red Raiders, Texas Tech sports information director Ralph Carpenter was the picture of professional objectivity when the Aggies rallied for a 72–72 tie late in the SWC tournament finals. "Hey, Ralph," said Bill Morgan, "this... is going to be a tight one after all." "Right", said Ralph, "the opera ain’t over until the fat lady sings."

In the same newspaper on November 26, 2006, Steve Blow followed up the discovery by contacting Bill Morgan about the incident:[4]

Bill vividly remembers the comment and the uproar it caused throughout the press box. He always assumed it was coined on the spot. "Oh, yeah, it was vintage Carpenter. He was one of the world’s funniest guys," said Bill, a contender for that title himself.

The 1976 use of the phrase was discovered by Fred R. Shapiro, who published it in The Yale Book of Quotations. It had previously been attributed to sportswriter and broadcaster Dan Cook, who used the phrase after the first basketball game between the San Antonio Spurs and the Washington Bullets (now the Washington Wizards) during the 1978 NBA Playoffs. Cook used the line to illustrate that while the Spurs had won once, the series was not over yet.[5] Shapiro called this a notable example of misattribution.[6]
