The In A Lifetime collection captures Clannad's incredible and enduring body of work which has, over 16 studio albums, created a legacy that's influenced a generation of fellow Irish musicians and artists.

After a decade which saw them release five hugely influential and groundbreaking albums, in 1982 Clannad reached wider recognition when they recorded Theme From Harry's Game for a powerful three-part TV drama depicting the troubles in Northern Ireland. The song became a commercial success upon its release as a single, peaking at number 2 in Ire-land and number 5 in the UK, winning an Ivor Novello award and later being used in the movie Patriot Games. It remains the only UK hit single to be sung entirely in Irish.
