This jig, when played on accordion anyway, sounds like it comes right out of a Scottish country dance band repertoire. The last 3 notes of the first line need to be played an octave up from the original but I think it fits nicely. Paddy O’Brien was a famous accordion player and composer who died in 1991. A book of his compositions is for sale which makes me hesitant to share the sheet music, though the dots can be had from thesession.org which is where I found them when researching a previous tune of the month: The Maid in the Cherry Tree which is also known as the Curragh Races; however, I don’t really have sympathy for composers’ rights holders when they let their book fall out of print/availability. Since the book seems to no longer be in print, until that’s rectified, I’ll post the sheet music here.
