“Church is never out until they stop singing”

“Church is never out until they stop singing” is another way of saying “It ain’t over ‘til it’s over.” “As long as the organ is playing church is not out” was cited in a newspaper in 1872.
   
The expression became widely known in the 1890s. “Church is never out till the people get through singing” was cited in 1894. “Church is not out until the last hymn is sung” was used in 1895 to mean that a baseball team still had a chance to come from behind and win a baseball game. “Church is never out till they stop singing” was said by New York politician Chauncey Depew about someone’s chances to be president.
 
“The opera ain’t over until the fat lady sings” is a modern variation of this saying.

There is an old saying that “church is not out ’till the singing’s done,” and with the narrow margin which the Democrats have in the Senate, it is believed that at least the wool and sugar schedules are still in the balance.

Whether he can secure the return of enough Democrats to block the plan of the Republicans is problematical, but in any event the political pot will be boiling for the next few days, and the old saying that “church is never out ’till the singing’s all done” is very apropos in this instance.

Commissioner Jerry Mebus, too, took an honorable mention for the quotes he dreamed up and never used.
 
Mebus has been waiting almost a full year for the right situation so he can drop one of his best. “Don’t leave the church until the fat lady sings.”
