Two traditional Irish single "slides" (a type of jig used for a particular dance). Merrily Kissed the Quaker has its roots in a Scottish Jig, Merrily Danced the Quaker's Wife. Padraig O'Keeffe's Slide is named after a celebrated Sliabh Luchra fiddler. It's also known as Dennis Murphy's Slide, after another fiddler whom O'Keeffe taught.
