Clannad features lead singer Moya Brennan and her brothers, Ciar?n and P?l Brennan. Her children, Aisling and Paul Jarvis, are also part of the touring band. Clannad hit the No. 5 spot on the U.K. singles chart with the 1982 track “Harry’s Game,” and four years later had some success with the song “In a Lifetime” featuring guest vocalist Bono from U2. With a rich discography and a sound that crosses into traditional folk and Celtic with modern elements of instruments like synthesizers and an emphasis on lush vocal harmonies, the show should be a transcendent and fitting farewell.
