Edit...
My wife and I, stopping off on our way to Miami before we got married, stopped at a diner in Cocoa Beach. They were having a semi-final event for a karaoke competition. We saw a wrinkled, sun-tanned old woman in a pink terry-cloth sweat suit get up and do a rendition of "Crazy" by Patsy Cline- she was very good, and she gave us the willies! It was right out of a David Lynch screenplay. She had a total take on it, like she'd written it- she brought the "Crazy" home. It was devastating, and very entertaining.
Karaoke can be ok.
