... ahem...I have the sheet music, purchased many, many years ago (probably in the early 60's).The sheet music says "I hear a breeze..."
Also, it has choices for laddie or lassie words. The laddie is a whistlin' and the lassie is smilin' and later a-sighin'." It looks like Joe's words are for the lassie and Ferrara's for the laddie.
The sheet music also spells Shannon, "Shanon."
...so much for the official sheet music.
