The Main Street Quartet doesn't just sing modern songs in barbershop harmony. It weaves them into a complex and perfectly performed stand-up comedy routine.
Their whole composition is called "Good Old Days." In it, the members explain that today's songs will become oldies soon enough and, eventually classical music.
Their performance includes Britney Spears's "Oops! I Did It Again," Mark Ronson's "Uptown Funk," Meghan Trainor's "All about That Bass," and Psy's "Gangnam Style."
But their pauses for comedy riffs are even funnier than their singing!
