Jamison, a Philadelphia-based Celtic rock band, will perform “An American Celtic Christmas” at 7:30pm on December 20 at the Keswick Theatre.

Jamison, founded in 2003, started doing a Christmas show with Irish dancers and other guests in 2011. According to founding member Frank Daly, the show was relocated to the Keswick in 2019.

“Last year, it sold out, which was incredible,” Daly said.

The family-friendly performance features a 12-piece band, including a fiddle, mandolin, accordion, and a tin whistle backed by a full rock band and vocalists. A professional choreographer works with the dancers, Daly said.

In November, Jamison will also be playing Preston & Steve’s Camp Out for Hunger for the 10th consecutive year, as well as the second annual Glenside St. Patrick’s Day festival in 2026.
