Delightful Barbershop Quartet Performs on Delayed Flight

A delayed flight was music to these passengers' ears.

Well, not quite, but everyone on this plane that was delayed due to flight maintenance got an unexpected treat when a barbershop quartet that was onboard broke out into song, putting a smile on all the passengers' faces.

Suddenly, sitting on the runway with nothing but time and a small bag of pretzels didn't seem so bad.
