Normally, being stuck on the tarmac induces tuts and frowns, but passengers on a flight to New Orleans were all smiles when they were given a special in-flight performance. While the plane was delayed on the tarmac for maintenance, flight attendant Kari Mann realized there was a barbershop quartet on board so she asked them to sing and filmed the performance. Four members of the Port City Sound barbershop quartet broke into song and entertained passengers with a rendition of The Drifters' classic tune Under the Boardwalk.
