MILLIONAIRE screwup

[Bapopik at AOL.COM]

   Oh, Reeg!
   David Shulman pointed out that one of the answers on a recent WHO WANTS TO BE A MILLIONAIRE? was wrong.  I found it on the web.  It was the 5-13-01 show, with this question:

For $300:  The expression "It ain't over until the fat lady sings" originally referred to what kind of event?
B) Opera.

   That was given as the correct answer.
   However, the expression was also used in southern churches.  CHURCH ain't over until the fat lady sings.
   This looks like a correcting job for Fred Shapiro.
