For the fourth year in Augusta, Harry O'Donoghue and Carroll Brown will perform A Celtic Christmas, a mix of traditional Christmas music, Irish music and spoken-word pieces.
"The whole show is varied and will not be your typical Christmas concert," O'Donoghue said.
Guests will recognize familiar tunes such as Winter Wonderland and will perhaps discover lesser-known numbers such as Christmas in Killarney.
Some spoken-word pieces will be recitations of poetry, including Patrick Kavanagh's A Christmas Childhood.
Brown and O'Donoghue, who perform traditional Irish music in Irish pubs, collaborated with fellow musician Frank Emerson on A Christmas Postcard in 1999.
They went on tour to promote the album, which became so successful they've been doing it since. Emerson stopped touring for health reasons, Brown said.
For most of the year, the singer-songwriters concentrate on their solo careers. O'Donoghue is the host of The Green Island Radio Show on Georgia Public Radio.
"It's a special time for us, too, because we get to hang out together," O'Donoghue said.
Jeff Ryan, the president of the local chapter of the Ancient Order of Hibernians, said he hopes to bring more Irish cultural events to the area.
"A lot of people are Irish at St. Patrick's time, but they're not Irish anywhere else around the year," he said.
