Callanish, a Celtic band based in central Pennsylvania, plays Irish and Scottish music in the traditional style. Its repertoire includes lively jigs and reels, haunting airs, and rollicking songs from Ireland, Scotland, and elsewhere in the British Isles. 

The four women of Callanish are Patty Lambert, Betsy Gamble, Louisa Smith, and Holly Foy.  Patty Lambert plays wooden flute, whistle, and concertina. Formerly on the faculty of the Music Academy, she now teaches privately in her home. Betsy Gamble plays fiddle, viola, and pipes and is a piper in the Nittany Highland Pipe and Drum Band. Lead singer Louisa Smith is a 2009 graduate of the Penn State School of Theatre and a classically trained vocalist. She also plays bodhran, spoons, and other percussion. Holly Foy plays guitar, bouzouki, and banjo.

The band has performed festivals and events throughout the region, including at the Williamsport Community Arts Center, where the band opened for Women of Ireland.
