Q I saw a group called Celtic Woman on PBS and was captivated. Please tell me about them.
—Maria MacKay, Richmond, Ky.
The five young Irish women in the spellbinding group Celtic Woman mix traditional Irish tunes with timeless classics and contemporary numbers. Their new Christmas CD, A Christmas Celebration, features "O Holy Night," "Little Drummer Boy" and "Silent Night" alongside the St. Thomas Aquinas hymn "Panis Angelicus," the 12th-century Irish song "The Wexford Carol" and the traditional Celtic ballad "Don Oiche Ud I mBeithil." The group's self-titled 2005 debut CD spent 68 weeks at No.1 on the sales-based Billboard World Music Chart, setting a new record.
