According to an article in the local newspaper the Sligo Champion, Clannad will be one of the guests in the Late Late Show this Friday 13th September. The show starts at 9.30PM on RTÉone. I'm trying to get a final confirmation on this.
After their appearance in the show the band will travel to Sligo to perform on Saturday 14th, celebrating the opening of a brand new building of the Summerhill college. Pól Brennan is a past pupil of the school. The concert takes place in the Knocknarea Arena in IT Sligo.
Update: Clannad and Duke Special are rehearsing for the LateLate Show. So the song for tonights performance will be "Brave Enough" i guess.
Update 2: If you couldn't make it last night. Here they are, Clannad on the LateLate Show with "Brave Enough".
