The Maids of Mitchelstown is a wonderful tune that was made popular by The Bothy Band, on their album Out Of The Wind Into The Sun. I believe the original key was D minor, and I learned it in that key from my friend Tom Delany. It is also quite common in E minor in sessions around Doolin, as recorded by the great band Moher. Below are the two versions.
