McCafferty

"McCafferty" (Roud 1148) is an Irish folk ballad about British Army Private Patrick McCaffrey, executed in 1862 for the "fragging" of two officers. It is particularly popular in Ireland, where Pte. McCaffrey came from, and was recorded by The Dubliners. In the British Army it was allegedly a court martial offence to sing the song, but that is a legend. In fact, according to A.L. Lloyd "during World War II it was adopted as the anthem of a parachute commando regiment, the 2nd Special Air Service."

The song is set to the traditional Irish tune "Cailín Óg a Stór", which is the same melody used for "The Croppy Boy". Provided by Wikipedia
