The Mason's Apron

The Mason’s Apron is a traditional Irish reel, also known as Braes Of Glenorchy, Isla, Lowrie Tarrell, and Mason Laddie. Originally an eighteenth century English tune, it has long been popular in Ireland and appears to have been first recorded by New York accordion player John J. Kimmel in 1915. The earliest published version is found in Riley's Flute Melodies Vol 2 (New York : 1814 -1830), compiled by Edward Riley (1769-1829).
You hear the version of Matt Molloy together with The chieftains.
