Fields of Athenry
Wild Mountain Thyme (Scots/Irish crossover)
Danny Boy.(Irish/English crossover). Hackneyed, but truly Irish favourites.
Do Pogues songs count.. ? what is folk what is pop? As soon as you use the word 'panel' then cultural bias and trendiness comes into it... the emperor's new clothes syndrome. It is no longer Ireland's favourite song but whichever writer or recording has kudos with the panel members and their own backgrounds.
