Elva Ruby Miller, who recorded under the name Mrs. Miller, was an American singer who gained some fame in the 1960s for her series of shrill and off-tempo renditions of popular songs such as "Moon River", "Monday, Monday", "A Lover's Concerto" and "Downtown". An untrained mezzo-soprano, she sang in a heavy, vibrato-laden style; according to Irving Wallace, David Wallechinsky and Amy Wallace in The Book of Lists 2, Miller's voice was compared to the sound of "roaches scurrying across a trash can lid."

"Monday, Monday" is a 1966 song written by John Phillips and recorded by the Mamas & the Papas, using background instruments played by members of the Wrecking Crew for their 1966 album If You Can Believe Your Eyes and Ears. Denny Doherty was the lead vocalist. It was the group's only #1 hit on the U.S. Billboard Hot 100.
