Did you see the youtube clip of passengers delayed on a US airways flight? 

A video of a barbershop quartet entertaining bored passengers has racked up more than 3,300,000 views on youtube.

So here on the Right Hook we decided we needed our own barbershop quartet.

We invited the Key Notes into studio today to chat about the appeal of barbershop and to perform a special Right Hook version of 'Ireland's Call' ahead of the opening weekend of the Six Nations. They made George Hook's day.

Watch the Key Notes perform Ireland's Call:
