From the recording Another Season's Promise
Sí Beag, Sí Mór, "Small Fairy Mound, Big Fairy Mound", is an Irish folk tune. The title uses the word 'Sí', the Irish Gaelic for 'fairy mound'. The tune is usually attributed to blind harpist and singer Turlough O'Carolan (1670 – 1738) as his first song, written to the tune of "The Bonnie Cuckoo".
One author describes it as a "beautiful old Irish air, usually played simply and leisurely, and occasionally played as a waltz". Sí Mór (Sheemore) and Sí Beag (Sheebeg) are the names given to two small hills, situated close to each other in south County Leitrim, said to be ancient burial sites, and to a site in Carolan's birth county of Meath.
The Snowy Path is an Irish Slip Jig... don't know much more than that.
