    • The character Carmen-Ghia refers to Bizet's Carmen; Don Octave and Donna Ribalda play on characters in Mozart's Don Giovanni; Il Commendatoreador hits both operas at once. The name references the 1960's Volkswagen sports coupe, the Karmann Ghia.
    • The shorter recorded version of the opera is hosted by "Milton Host" and has an "Opera Whiz" feature.
