The Stoned Guest

This musical work, while touted as "P. D. Q. Bach's Half-Act Opera: "The Stoned Guest"," is actually the work of Peter Schickele. The title is a play on the subtitle of Don Giovanni by Mozart, "The Stone Guest", as well as the opera "The Stone Guest" by Alexander Sergeyevich Dargomïzhsky. The work is a parody of classical opera, although some critics consider it to be the equal of many classical works in technical ability.Fact|date=February 2007 The opera appears on the 1970 album of the same name.

The loose story combines elements of "Don Giovanni" with elements of "Carmen" by Georges Bizet. Some character names, such as "Don Octave" and "Donna Ribalda" play on the Mozart opera, referring to Don Ottavio and Donna Elvira respectively, while the castanet-clicking "Carmen Ghia" plays on the title character of Bizet's opera (and puns on the Volkswagen Karmann Ghia). The "Commendatoreador" plays on both operas at once, being a combination of "Il Commendatore" and the toreador Escamillo. The orchestral accompaniment for Donna Ribalda's opening aria, "Let's face it—I'm lost", bears more than a passing resemblance to the "Rex tremendae majestatis" from Mozart's "Requiem".

At one point in the opera, the rival divas Carmen Ghia and Donna Ribalda have a contest to see who can hold a note the longest.

The ending parodies many classical operas, "Don Giovanni" in particular, by apparently ending in tragedy, then having a completely unmotivated happy ending.
