Last month, a US Airways flight from Indianapolis to New Orleans was delayed for maintenance after everyone had already boarded. Flight attendant Kari Mann learned that 4 of the passengers were a barbershop quartet called Port City Sound. She asked them to sing and they obliged. Mann writes that, “The mood changed and our passengers were awesome for the whole 5 hours they were on the plane!”

This is an idea I posted at Halfbakery.com: Make Your Carpool a Barbershop Quartet.
A two-CD set and instruction book could lead a carpool through the process of assessing singing ability and range, basic breath control and other technical considerations. The second CD would then teach the group some classic Barbershop standards.
