This barbershop quartet performed for passengers on their delayed flight

When a group of airline passengers were delayed on the tarmac, a quartet of gentlemen found the perfect way to keep every one entertained.

Port City Sounds, a Barbershop Quartet were on the flight to New Orleans when they were delayed on the ground for maintenance, for a number of hours.

"Our flight to New Orleans today was delayed for maintenance AFTER we had boarded (I'm a flight attendant)." says Kari Mann, in the description on the youtube video.

"I started talking to the passengers and realized we had a barbershop quartet in our presence. I asked them to sing and most of the passengers began video taping!"

It was such a great moment... The mood changed and our passengers were awesome for the whole 5 hours they were on the plane!"

"One of my favorite moments!!! Thank you to Port City Sound for creating a wonderful memory!!! #usairways"

Why can't all flight delays be like that? Rather than sitting there in silence wondering how many free things you can get from the airline because of it.
