This is one of the most popular Irish folk songs around. It has been recorded by the Dubliners, Thin Lizzy, Metallica, and many, many others.
I have played this song countless times, usually on bodhran and occasionally on guitar, but always backing someone else. In fact, other than supplying backup vocals on the chorus, I had never sung this song until about an hour before I recorded this. I even had to go online to double check some of the lyrics.
