New York�'s Ceann is an Irish rock band that you don�t need to be Irish to enjoy. The quintet, ranging in age from 28 to 32, are taking the East Coast by storm with hyperactive, light-hearted ditties about fake pirates, Vikings, green beer and girls who are only �Pretty on the Inside,� which was the NPR song of the day on June 11. Ceann (pronounced �key-ann�) have been compared to a funnier, acoustic version of Flogging Molly and the Dropkick Murphys. �The Worst Pirate Song� has been downloaded more than 50,000 times on the band�'s Web site. If you think the band is anything but a good time, guitarist and vocalist Patrick Halloran revealed that the band�'s original name was Ceann na Caca, which is Gaelic for �Poopoo Head.� Halloran said the band�'s stock has been rising since �The Worst Pirate Song� and �Pretty on the Inside� hit. �"I got an e-mail from the girl I went to my high school prom with. She said she heard this obnoxious song and my name on the radio and she had to listen,"� Halloran said. This show will be Ceann�s second at Nine Irish Brothers. �"The Midwest is where we�'re received the best. They get our mentality and sense of humor,"� the guitarist said.
