Tir na n-Og were an Irish group comprising Sonny Condell and Leo O Kelly who released at least three albums between 1969-73 or thereabouts. To call them irishippyfolk would not do justice to the ravishing acoustic interplay between the pair & the charm of their songwriting. Both artists went on to have solo careers, Condell particularly and both reunite for the odd Tir na n-Og gig in Ireland. Their second album " A Tear and A Smile" is one of my alltime favourites.
