Oh yes! “The “fake opera” is a riot!
The “Fake operas’ in the Nelson Eddy “Phantom” were Johann Strauss and Tchaikovsky. From what I understand, the composers were on strike when that movie was made, so they used existing music.
My cousin dragged me to see “Aspects of Love” when I last visited Philly in 2011. ALW graduated from one commercial hit per show to using the same damn song over and over again throughout the show. It’s catchy but boring.
