A group of professors rocked out Thursday afternoon, playing Celtic music to celebrate St. Patrick’s Day.

The group, who call themselves the Library Leprechauns and performed in Java City at Helm Library, is made up of Jack Montgomery, associate professor in library and technical services, Molly Kerby, assistant women’s studies professor, Tom Hunley, associate English professor and Lesley Montgomery, a psychology office assistant.

Jack Montgomery said the group had only been together for three weeks but that he and Kerby have known each other for more than 10 years, often performing together.

Kerby said they’ve played rock, folk and Celtic music together.

“Jack and I collectively are in five bands,” Kerby said.

She said Jack contacted her in January to form a small band, and she agreed.

“Tom bought a bass, he called Jack, and they came up to me and was like, can we play together?” Kerby said.

Jack Montgomery said that the group decided to perform today because the music they traditionally play and St. Patrick’s Day fell hand in hand.

“I’ve been doing Irish music for a long time and it just seemed appropriate,” he said. “Also, a lot of people have Irish ancestry.”

He also said St. Patrick’s Day isn’t just a day for celebrating Irish heritage, but all different types of heritages.
