Last month, a U.S. Airways flight wound up delayed for 5 hours due to maintenance issues. This was a mostly full flight. To everyone's good fortune and surprise, "Port City Sound," a popular Maine based barbershop quartet were on-board and entertained the passengers to help pass the time!

Kari Mann, a flight attendant on board, managed to get her video camera rolling to document what was happening. She said this was one her fondest memories on a plane! She later posted the video on YouTube and it went viral; over 4 million views!

Sandra and Mike had the guys on HOM Mornings last week for Valentine's Day. Check it out!
