TG Lurgan and Seo Linn - Avicii Vs Lurgan - "Wake Me Up" as Gaeilge

Seo Linn is the group we heard at The Battery at the 1916-2016 centennial of the Irish Easter uprising.  TG Lurgan is the lead singer here.  I heard them again at Maguires Pub on Roosevelt Avenue, Woodside, Queens.  I don't know a word of Gaelic, but the people in the crowd evidently do.
