I can't even remember who I learned this from, let alone its name. I've called it "Masúrca Gan Ainm" as it looks a bit more exotic then "Untitled Mazurca". It was nice of the committee in Dublin to take the trouble to make up an Irish word for "Mazurka".
m. mooney and frankie kennedy recorded this mazurka on their ceol aduaidh album.they called it by her father name, same as another mazurka in the set. marin
This tune is in the Comhaltas Foinn Seisun #1 book as John Doherty’s Mazurka, equally on www.thesession.org under the same name.
