Na Casaidigh, also known as The Cassidys, are an Irish traditional group from Gweedore, County Donegal. Comprising brothers Aongus, Seathrún, Ciarán, Fionntán, Feargus, and Odhrán Cassidy, the band's musical journey began under their father's influence, a church choirmaster who fostered their love for Gaelic music. Their breakthrough came during U.S. President Ronald Reagan's visit to Ireland in the mid-1980s, performing at a state banquet televised live from Dublin Castle. Na Casaidigh released their debut album Na Casaidigh in 1981, followed by Fead an Iolair (1984) and The Cassidys Live (1985). They gained international recognition with performances at Carnegie Hall in New York City. Subsequent albums include Off to Philadelphia (1996) and Singing from Memory (1998). The group has also performed classic Irish songs such as "Bó na Leathadhairce" and "Báidín Fheilimí".
