Celtic Christmas Philadelphia – An American Celtic Christmas
An American Celtic Christmas returns to the Keswick Theatre in Glenside, PA on Saturday, December 19, 2026 at 7:30 PM. Celebrating its 16th year, this Philadelphia-area holiday tradition brings together high-energy Celtic rock, Irish music, world-class Irish dance, Christmas favorites and special guest performers for one unforgettable night.
Presented by Philadelphia Celtic rock band JAMISON, An American Celtic Christmas combines the energy of a live Celtic rock concert with the music, dance and spectacle of a Christmas stage production.
A Philadelphia Celtic Christmas Tradition
An American Celtic Christmas began in 2012 when JAMISON created a holiday show combining the band’s Celtic rock sound with Irish dance and Christmas music. Over the years, the production has grown into an annual Philadelphia-area holiday tradition, bringing musicians, singers and Irish dancers together on the Keswick Theatre stage.
Rather than a traditional Christmas concert, the show moves between high-energy Celtic rock, Irish music, Christmas favorites, contemporary influences, featured performers and Irish dance.
Celtic Rock, Irish Music and Christmas Favorites
At the center of An American Celtic Christmas is JAMISON, the Philadelphia-based Celtic rock band formed in 2003. JAMISON combines Irish and Celtic music with rock, pop and contemporary influences, creating the high-energy sound that drives the Christmas production.

The American Celtic Christmas Irish Dance Troupe features accomplished dancers from throughout the Philadelphia tri-state area, including performers who have earned national and international competitive titles.
The combination of live Celtic music and precision Irish dance gives the production the scale and energy audiences have come to expect from the Keswick Theatre show.
