My students love breaking apart challenging texts to find the meaning. They were getting tired of the American folk songs (or as some of them said, "it's too easy to figure out"). So I upped the challenge and busted out some old English and Celtic songs. They were also requesting Irish songs for St. Patrick's Day.
Danny Boy was one of the simpler Irish songs I introduce to my students and they quickly figured out the meaning and were very interested in the various scenarios that could have led to the creation of the song (https://en.wikipedia.org/wiki/Danny_Boy). We also listen to different recordings of the song for comparison activities.
I use an accompaniment from a collection called "Sing with the Symphony" when teaching the song. But regardless of the accompaniment you use the melody and tempo should be the same. Each line will scroll on click to make it easy for students to follow along.
Knowing that there are different versions of this song I went back to the original text. Check the notes in the PowerPoint for ELL friendly definitions for tricky words students may not know
