It would be nice if you specified who the composers of the pieces were. I have never played a piece called "Tales of the Emerald Isle," but I have played three different pieces that were each called Bolero. A Bolero is simply a Spanish dance in triple meter or the music for that dance. There are quite a few composers who have written music in that style and called their piece Bolero after their influence from an actual bolero. So, I've played an orchestral bolero by Ravel (with a great flute solo), a flute and piano bolero by Genin, and another flute and piano bolero by Pessard.
